I study physics, and I want to cross-test the mechanical manufacturing and automation of Shanghai University. But just learn mechanical design and mechanical principles, okay? I don't appreciate the advice of internet experts. Generally, the postgraduate entrance examination for mechanical majors only takes these two courses or one of them. Mechanical professional courses include theoretical mechanics, material mechanics, electrical technology, sensors, hydraulic fluid control principle, mechanical manufacturing technology, automatic control principle, numerical control, PLC technology, measurement and detection technology, metal processing technology (cold and hot processing technology, special processing technology, etc.). ) and engineering materials. The principle of single chip microcomputer, and some necessary software for mechanical students, such as CAD, pro-E, ansys, and so on. But if you are interested in machinery, you can go to graduate school and learn slowly. Alternatively, we can focus on those modules in communication design or control development.
