| 摘 要： | 本文对样车进行了系统分析和试验诊断，建立了整车加速纵向振动模型，并加以仿真。研究结果表明样车加速时车身的纵向振动低频成分（3.9Hz)由动力传动系扭振所引起，高频成分（7.9Hz)由发动机第五悬置与车体限位框碰击所产生。在考虑生产的可行性和仿真验证的基础上，提出了改进方案。

| Abstract: | In this paper,the analysis and experiments on a vehicle system are carried out and a vibration model is built to simulate vehicle surge. It is clarified by experiments and simulation model, that the vehicle surge is caused by both the torsional vibration of power train (3.9Hz) and the collision of the fifth pad of engine mount with the limit stop on car body (7.8Hz). Accordingly,some feasible solutions to vehicle surge are given. |
