Theoretical Mechanics is one of the technical basic courses in mechanical profession.The course is logical,systematic and theoretical,and the students are ambiguous about the mechanical relations taught in the course,which makes it difficult for them to understand the textbook part of the knowledge.Virtual prototype technology can be used to analyse the corresponding mechanical structure,in order to let the students understand the theoretical mechanics knowledge more easily,and to enhance the students'interest in learning theoretical mechanics knowledge.Take the hinged four-bar mechanism and its evolution mechanism as an example,the virtual prototype technology is used to carry out a simple analysis.
