| 摘 要： | 针对某汽车制造企业制造并投放市场的某大型载货汽车在行驶几个月时出现的车架早期裂纹甚至断裂的情况,利用有限元分析软件ANSYS对其进行了有限元建模,模态分析和在路面激励下动态响应分析,并对车架进行多种路况下的动态应变电测试验和振动试验.有限元分析结果表明,路面激励在8Hz附近时,车架应力及位移响应较大.动态试验中车架综合...

| Abstract: | Aiming at the problems that cracks and fracture appeared in the vehicle frame of a brand heavy truck after driving a few months,a finite element model was established to analysis structural vibrating modes and random dynamic vibrating responses excited by road configuration by using software ANSYS.The finite element analysis results show that stress responses and displacement responses of the frame caused by 8 Hz road excitation are quite large.Dynamic strain measurement and vibration experiments were perfo... |
