Study on lightweight design of a mine explosion-proof rubber-tyred vehicle

In order to reduce the whole mass of a mine explosion-proof rubber-tyred vehicle,the CAD model and finite element model of the front and the back frame are established respectively according to driving conditions and load conditions of the rubber-tyred vehicle,then the strength of the frame is assessed through stress analysis with the finite element method.Based on the stress analysis results,lightweight design of the frame is carried out,and the mass of the frame is decreased by 36%.Analysis results show that the stress intensity of the optimized frame model is less than the material allowable stress,and the optimization results are valid,which provides theoretical basis for the improvement design of rubber-tyred vehicles.
