滚动轴承的物理参数识别

Identification of physical parameters of rolling bearings

针对滚动轴承的测振状态,建立了一个两自由度振动识别结构的模态参数,避开振型误差较大的缺点,结合实验模型和分析模型,识别出滚动轴承的物理参数。附图5幅,表4个,参考文献4篇。

According to vibration test condition of rolling bearings, the model parameters of vibration identification design with two degree freedoms are set up, and the defect of bigger error for vibration model is avoided, combining with the relation bet - ween experiment model and analysis model, the physical parameters of rolling bearing can be identified.
