Research on Dynamic Stress Numerical Simulation of Mine Explosion-proof Rubber-tyred Vehicle

Wang Zhi-shuai

Abstract

As load factors for Mine explosion-proof rubber-tyred vehicle in mine are extremely complex,multi-body dynamics model and finite element model of frame were established respectively.Virtual prototyping technology was used to simulate real load conditions for vehicle,then random excitation peaks of rectangular pit road condition were extracted,which would be applied for finite element dynamic stress analysis of vehicle.Finite element analysis results indicated that maximum dynamic stress of entire frame is conforming strength requirements.
