摘要
利用台架检测车架的弯曲刚度和扭转刚度,运用台架进行车架弯曲疲劳试验和扭转疲劳试验,快速检验车架的可靠性,并运用有限元分析法验证台架试验状况下的车架的刚度和车架的应力分布情况,结合车辆的路试情况来判断台架试验的准确性。
Use bench testing frame bending stiffness and torsional rigidity, the use of the gantry frame bending fatigue tests performed and torsion fatigue test, rapid test the reliability of the frame, and the use of finite element analysis to verify the situation under bench frame stiffness and stress distribution frame, combined with vehicle road test case to determine the accuracy of the bench.
