A Research on the Methods of Fatigue Analysis for Vehicle Body Based on Real Road Conditions

Abstract:

Complex road excitation,has long been the key and difficulty of simulation technology for vehicle fatigue. The main error source of the technology is the deviation that virtual road and simulation speed are not true of proving ground test. An improved method was presented. The long-distance virtual road which consisted of a variety of typical pavements was built and used as the excitation, and the measured speed was applied to the virtual test. So the virtual test could be a true reflection of the road conditions of the proving ground, and improve the accuracy of the load that the fatigue analysis required. Finally, the linear superposition method was used to rapidly predict the fatigue life. In the durability project of a certain vehicle,it was proved that the virtual test could reproduce the road conditions of Hainan proving ground by comparing with the measured values of accelerations of wheel hub. The example of the front wheel cover plate proved that this method could efficiently and accurately predict the vehicle body fatigue life.
