Motion simulation design of crank-connecting rod mechanism of automobile engine

In this paper, the crank-connecting rod mechanism of Santana 2000AJR automobile engine is modeled by UG8.0 software with CAD technology, and then the motion simulation module is used to create the motion drive. After pre-processing and post-processing, the motion simulation design of the crank-connecting rod mechanism is completed. In the development of automobile, the motion simulation technology can simulate the motion law of crank-connecting rod mechanism and replace the complicated physical experiments in practice, shorten the calculation cycle and cost, and lay a foundation for optimizing the design of crank-connecting rod mechanism.
