About mechanical design:

Machine design is a working process of conceiving, analyzing and calculating the working principle, structure, motion mode, transmission mode of force and energy, materials, shapes and sizes of components, lubrication mode, etc. According to the use requirements of the machine, they are converted into specific descriptions as the basis for manufacturing. Mechanical design is an important part of mechanical engineering, the first step of mechanical production, and the most important factor to determine mechanical performance. The goal of mechanical design is to design the best machine under various limited conditions (such as materials, processing capacity, theoretical knowledge and calculation means, etc.). ), that is to make an optimal design. Optimization design needs to consider many requirements, generally including: the best working performance, the lowest manufacturing cost, the smallest size and weight, the most reliable use, the lowest consumption and the least environmental pollution. These requirements are often contradictory, and their relative importance varies with different types and uses of machines.
