转盘轴承实验台是一种根据转盘轴承工作特点设计的专用实验设备。本文采用Simulink软件中的SimMechanics模块搭建实验台机械结构的仿真模型。仿真模型是在有限元计算的基础上，将实验台结构简化为线性弹簧。仿真模型中的转盘轴承采用Zupan等提供的解析法简化。通过滚珠最大应力验证仿真模型结果的正确性，参照标准是美国国家可再生能源实验室提供的经验公式。SimMechanics仿真结果与经验公式、有限元模型结果比较，误差在10%以内，误差可以接受。SimMechanics仿真模型的精度不及有限元模型，但仿真模型实现了机械系统与控制系统在同一仿真环境中搭建，并且仿真模型的计算成本远小于有限元模型。

Wheel bearing test bench is a special experiment equipment based on the work features of wheel bearing. This paper uses SimMechanics module of Simulink software to build bench mechanical structure simulation models. The simulation model simplifies the bench to a linear spring on the basis of finite element method. The wheel bearing of simulation model uses analytical method provided by Zupan. The correctness of simulation results is validated by balls maximum stress, the reference standard is the empirical formula provided by U.S. National Renewable Energy Laboratory. Compared to SimMechanics simulation results, empirical formula and finite element model results, the error is acceptable when less than 10%.
