摘　　要：为了在节约试验成本的同时保证试验结果的科学合理性,运用相似理论对回转轴承模型试验进行分析,采用量纲分析法推导出回转轴承模型试验所需要的相似准则,并进一步讨论模型试验应遵循的条件及其放宽。最后,通过回转轴承结构模型的试验物理量的相似比计算说明上述相似准则的应用。In order to ensure the rationality of the test result and make the test cost as low as possible meanwhile,the similarity theories are applied to analyze the slewing bearing experimental model. The dimension analysis method is used to deduce the similarity rules that are required in the model test. Test conditions are further discussed. As an example ,the similarity ratios of the model physical parameters are calculated to demonstrate their validity.
