Abstract: The dynamic similarity criterion of bearing cage was analyzed based on similarity theory.According to the model analysis theory,the similarity ratios of the main modal parameters were obtained to make an expanded model in the ratio of 3∶1,and test its dynamic performance.The inherent frequency of the real-size cage has been achieved from the test results,meanwhile the results were verified through dynamic response test on the bearing components.
