提出了一种轴承动力特性试验的试验方法，轴承用真轴承，转子采用模拟转子。计算模拟转子的一阶弯曲临界转速，使其与真实转子转速相同，同时保证轴承的工作转速、静载荷与实际工况完全一致。基于动力相似计算分析基础，提出了滑动轴承性能测试的试验方案设计，给出了滑动轴承性能测试的试验装置。

A method for bearing dynamic characteristics test is proposed in the paper,which uses a real bearing and a simulation rotor.The critical speed of the first bending the simulation rotor is calculated as the same as that of the real rotor.The working speed and static load of the simulation rotor are also exactly the same as the actual conditions.Based on the analysis of dynamic similarity calculation,the scheme and device for performance testing of sliding bearing are proposed.
