A virtual simulation experimental teaching system has been designed and developed to ad-dress the strong practicality of the"Mechanical Principles"course.The system includes five modules:planar mechanism cognition,planar linkage mechanism,cam mechanism,gear transmission,and dynamic balance principle.The system implements functions such as 3D animation display of mechanical compo-nents,motion simulation of various mechanisms,virtual disassembly and installation of experimental e-quipment,and virtual testing of various parameters of experimental devices.This system has strong in-teractivity and fun,which helps to improve students'learning enthusiasm and initiative.
