运用接触单元和两节点接触摩擦单元构建了接触和接触摩擦数学模型，基于此建立了轴承组件的有限元非线性数学模型，为证明该模型的正确性，利用开发的分析软件对轴承组件支承轴顶端内环某顶点的动态性能进行了计算分析，并进行了试验验证。理论计算结果和试验结果相对误差约为3．1％，在允许的误差范围内。这表明所构建的轴承组件的有限元非线性数学模型是正确合理的。

The math model for contact and contact friction is esablished by using contact element and two-node con-tact friction element.Based on this,the finite element nonlinear math model is built for bearing assembly.In order to demonstrate the validity of model,the dynamic performance for a vertex of inner ring at the top of supporting shaft in bearing assembly is calculated and analyzed by using developed analysis software,and the validation test is carried out. The relative error between theoretical computation result and test result is about 3.1%,within the range of error permit-ting.The result show that finite element nonlinear math model of bearing assembly is right and reasonalbe.
