摘要
针对铁路货车滚动轴承故障样本数据难获取的问题,提出一种基于Pro/E和ADAMS的滚动轴承仿真建模方法。分析了铁路货车滚动轴承各零件之间作用力关系,并利用Pro/E软件建立铁路货车滚动轴承模型。采用添加参考轴线系的装配方法,将轴承模型导入ADAMS中添加约束、接触和驱动力;采用刚柔共建方式,将外圈设置为柔性体,其他部件为刚性体。结果表明,仿真模型的振动特性与理论情况基本相符。
The fault samples for railway freight rolling bearings are usually difficult to obtain in practice.A modeling method for rolling bearings is presented based on Pro /E and ADAMS.The acting forces are analyzed among different elements of railway freight rolling bearings,and the model for railway freight rolling bearings is built by using software Pro /E.The model for bearings is imported into ADAMS to add constraint,contact and driving forces by adding refer-ence axis.By using rigid -flexible construction,the outer ring is set as flexile body,while other elements are taken as rigid body.The experimental result shows that the vibration characteristic of model is consistent with theoretical situa-tion.
