摘要
力矩刚性是轿车轮毂轴承的重要性能指标,显著影响轿车的行驶舒适性、转向平稳性以及安全性。介绍了力矩刚性的产生原理及测量方法,并应用ANSYS软件对力矩刚性进行有限元分析,得出轮毂轴承内法兰盘力矩刚性的有限元分析结果。在力矩刚性测量仪上做实验,得到实际的测量值。通过对比发现,在加载相同的力矩载荷时,有限元分析值与实际测量值很接近,证明了介绍的有限元仿真方案是行之有效的。
Moment rigidity is an important performance index of automotive hub bearing.It has a significant influence on the ride comfort,the steering feeling during the driving and security.It introduces the measurement method of rigidity,conducts finite element analysis of rigidity with ANSYS and gets the FEM analytic result.An experiment is done on the rigidity measuring instrument to get the actual measure-ment result.By contrast found that in the same moment load,the FEM Analytic value and the actual mea-sured value is very close.It proves that the FEM simulation program is effective.
