Abstract

The vehicle engine is affected by the external excitation force in the actual work, which will make the engine work in a bad condition and easily produce vibration and noise. Therefore, it is necessary to model the engine to control the engine vibration first. In this paper, a type of vehicle engine is taken as the research object, and the six-degree-of-freedom dynamic equation of the engine is established according to the Lagrange Method. The natural frequency of the engine vibration system is calculated by numerical and simulation analysis. The engine vibration is analyzed, and the two results are compared to verify the correctness of the model. This research lays a foundation for the vibration control of the engine.
