Reserch on Dynamic Simulation of Certain Mine Explosion-proof Transportation Vehicle Based on Virtual Road Excitation

According to loading characteristics and complex road conditions when it works of certain mine explosion-proof transportation vehicle used in mine,multi-body dynamics model and finite element model of frame were established respectively in this article.Virtual prototyping technology was used to simulate different load condition and road excitation characteristics,the specific road excitation peak waveforms were extracted,then obtain the dynamic characteristics by finite element method,the result can meet dynamic strength requirement of frame,provides basis and theoretical reference of improving frame design.
