It really makes me happy to come to XXX University with excitement. This is not only the first time to get in touch with the joy of college life, but also the longing for a better future. I will never regret choosing machinery, on the contrary, I will be proud, because machinery is a very good major and has a bright future. In addition, I like mechanical letters very much, and I will achieve something in the future.
Students majoring in mechanical design, manufacturing and automation mainly study the basic theories and methods of mechanics, microelectronics and cybernetics. They are trained by modern mechanical engineering majors, and have the ability to engage in port lifting and transportation machinery and control or fluid transmission and control dynamic die forming. The main subjects of this major are mechanics and mechanical engineering, and the main practical teaching links are military training and metalworking. Keywords: mechanical design, manufacturing and automation. The life machinery industry in colleges and universities is the foundation and pillar industry of a country and occupies an extremely important position in the national economy. It is closely related to upstream industries (such as steel, coal, nonferrous metals, etc.). ) and downstream industries (such as housing and consumer goods). ) and has a strong pulling ability. Mechanical manufacturing automation technology has always been the most active research field in mechanical manufacturing. It is also the main means for manufacturing enterprises to improve productivity and win market competition. Without a strong machinery manufacturing industry, it is impossible to realize the industrialization, modernization and informatization of the national economy.
The mechanical design, manufacturing and automation technology are discussed and prospected below.
I. World Machinery Manufacturing Industry
(1) Economically speaking, as an important part of the world economy, the development of the world machinery manufacturing industry is closely related to its external environment. Influenced by the change of economic cycle, it is not only sensitive to the economic cycle, but also shows a certain lag. Since the 1990s, the world machinery manufacturing industry has developed in great fluctuations, which shows its special position in the national economy, especially in industrial development, and is the basis for preventing economic "bubbles". The trade of machinery manufacturing industry is extremely regional, and the trade gap between developed and developing countries is very large. Developed countries continue to dominate machinery production and trade. Developed countries such as the United States, Japan and Germany attach importance to the development of equipment manufacturing industry, not only because its contribution rate in production, export, accumulation and employment ranks in the forefront, but also because equipment manufacturing industry provides important material technology for the development and production of new technologies and new products, and is an indispensable strategic industry for economic upgrading.
(2) From the technical point of view, the mechanical manufacturing automation technology has experienced three stages: rigid automation, flexible automation and comprehensive automation since it appeared in the 1920s. Integrated automation is usually associated with concepts such as computer aided manufacturing and computer integrated manufacturing. It is the synthesis of manufacturing technology, control technology, modern management technology and information technology, aiming at comprehensively improving the labor productivity of manufacturing enterprises and the response speed to the market. The pressure of environmental protection and the wide application of information technology have brought new opportunities and challenges to the development of mechanical manufacturing automation technology. High-tech, informationization, greening and globalization have become the general trend of development.
Second, China's machinery manufacturing industry
(I) Status quo of machinery manufacturing in China Since the founding of New China, after nearly half a century of development, especially in the past 20 years of reform and opening up, microelectronics technology has been widely used in machinery manufacturing, adopting advanced manufacturing technology, cultivating high-tech industries and enhancing the development potential; The product structure and technical structure of enterprises have been greatly adjusted, and great progress has been made in transforming traditional industries with microelectronics; We have mastered the core and key technologies of a number of major technical equipment and major complete sets of equipment, and our ability to serve all sectors of the national economy has been continuously enhanced. Through technical transformation, a number of advanced new, efficient and high-precision manufacturing technologies have been widely used in machinery manufacturing. The Ninth Five-Year Plan and the Tenth Five-Year Plan are important periods for the machinery manufacturing industry to promote structural adjustment, change the mode of economic growth and achieve stable and sustainable development. Great achievements have been made in the reform and development of machinery manufacturing industry: the technical level of a large number of important products has been significantly improved, and the technological innovation ability of enterprises has been continuously enhanced, providing a large number of technical equipment for national economic construction; The output of some important products has jumped to the forefront of the world, and the market share has been continuously improved; The proportion of economic aggregate in the world machinery manufacturing industry is increasing; Foreign exchange earned by export ranks first in all industries in China, and it has become the second largest industry in China with great development potential. China's machinery manufacturing industry has established a comprehensive and powerful material and technical foundation, and basically formed a national economic equipment system with independent manufacturing capabilities. However, the long-standing situation of low product quality, unreasonable product structure and industrial structure, and weak independent development ability in machinery manufacturing industry has not been fundamentally changed. Therefore, the process of machinery manufacturing catching up with the advanced level in the world has been delayed, and machinery manufacturing enterprises and products generally lack competitiveness in the international market. At present, one of the bottlenecks restricting the development of China's machinery and equipment manufacturing industry is the lack of technological innovation ability. The original innovation system of China's machinery and equipment manufacturing industry has not adapted to the requirements of international competition in the new period, and the new innovation system has not yet been formed.
(II) Trends and Prospects of China Machinery Manufacturing Industry The 16th National Congress of the Communist Party of China clearly put forward the requirements of building a well-off society in an all-round way and revitalizing the equipment manufacturing industry; In the report of the 17th National Congress of the Communist Party of China, President Hu also emphasized "improving the ability of independent innovation and building an innovative country", which is the core of the national development strategy and the key to improving the comprehensive national strength. A large number of national key projects, such as the South-to-North Water Diversion Project, the West-to-East Gas Transmission Project and the West-to-East Power Transmission Project, as well as the vigorous urbanization construction throughout the country, will promote the development of mechanical and electrical products and create market demand for the growth of machinery manufacturing industry; The worldwide industrial transfer provides opportunities for the development of China's machinery manufacturing industry. In today's increasingly globalized economy, the comparative advantages of China's machinery manufacturing industry, such as large processing capacity, low cost and abundant human resources, make it a realistic opportunity and great potential to expand the export of machinery products. At the same time, it also provides the possibility for China's low-cost mechanical products to become the processing center of the world. It can be seen that China's machinery manufacturing industry will maintain a good growth momentum and further play a pillar role in the national economy. In the report of the 17th National Congress of the Communist Party of China, President Hu clearly pointed out: "We must always keep a clear head, base ourselves on the greatest reality of the primary stage of socialism, scientifically analyze the new opportunities and challenges of China's full participation in economic globalization, fully understand the new situation and new tasks of the in-depth development of industrialization, informationization, urbanization, marketization and internationalization, profoundly grasp the new issues and new contradictions facing China's development, take the road of scientific development more consciously, and strive to open up broader development prospects for Socialism with Chinese characteristics.
With China's accession to the WTO and the continuous development and introduction of new technologies and techniques, foreign languages and computer applications will become the necessary qualities for every skilled worker in the future. The market needs compound talents with "one specialty and many abilities", and it is hoped that these talents will have the ability to continuously improve and develop (solid cultural foundation). If China wants to become a manufacturing power, it must have thousands of knowledgeable and skilled workers. The learning characteristics of this major require us to have a strong foundation in science and engineering, so I will strive to improve my own quality, learn professional skills, repay my motherland with my first-class technology and noble moral sentiments, and achieve the glory of my life!
University is an important turning point in life and a place to fly your dreams. Say goodbye to the era of naive fantasy, and enter a stage where you can show yourself and improve yourself. My life has turned a new page and entered an unprecedented stage. Maoming College is not my dream, but it is also the cradle of cultivating talents. How will I fly my dream here and put wings on my dream? I expect my youth to shine here.
People say: planning benefits, a planned life will be a meaningful life. I remember reading an article on the Internet the other day: "Three years wasted! Approaching graduation, I found that time is like running water! Only tears of regret ... If time can go back and everything can start all over again, maybe I will take an active part in various activities, maybe I will learn English well and love the class group, and maybe I will make some new friends on my own initiative. If I had understood this from the beginning, I wouldn't have found three years of college life so blank when I graduated ... "This is the sentiment of a college graduate. From this, I realized the significance of planning. In order not to regret in college, I made the following plans: First, learn my major well and pay attention to self-cultivation. In order to be able to plug in the wings of knowledge and soar in the highly competitive workplace three years later, I must study hard and master professional skills. At the same time, strengthen the cultivation of professional ethics and increase employment energy. Secondly, take part in more activities, show your talents and practice your ambitions. University is a platform to exercise yourself. In college, I will take an active part in various activities. On the one hand, challenge yourself. Because I am not a student who loves acting and has strong expressive ability, I want to overcome my shortcomings and let others find my advantages. On the other hand, enrich yourself. Some people say that work is full because of busyness, and life is happy because of fullness. After three years of college life, I will keep myself busy and full. I will strive to develop morally, intellectually, physically and aesthetically in an all-round way and become a compound talent that meets the needs of today's society. Third, try to learn the subject of tools well. I want to challenge English and computer. Although I have a lot of problems in this respect, I still set a goal for myself, that is, I must pass CET-4 and Computer National Test-2 before graduation. Maybe the goal is a little high, which seems difficult to achieve, but when I set a goal, I will have the motivation to move forward and I will go forward bravely. No matter how many storms I have experienced, I will go through them.
Finally, get ready to go. Because my major is order-based training. This will mean that we will practice in our junior year. Here, I want to experience the myth of self-reliance far from home. More importantly, I can develop myself better, enrich my experience and lay a solid foundation for better employment. The above is my preliminary plan for the university. Only when we can proceed from reality and plan our wonderful life, we will surely run towards a bright future. thank you
