基于性能退化的小子样电主轴可靠性试验研究
Research on Reliability Test Based on Small Sample Motorized Spindle Performance Degradation
摘要
Abstract
To avoid the disadvantages of reliability analysis on high-speed motorized spindle,a performance degradation reliability test method was proposed herein by two 170MD18Y16 motorized spindles.Firstly,according to the feature quantity and truncated time,a model of small sample mo-torized spindle was established with shaft end radial run out data to analyze failure life.Secondly,the characteristic life model of 170MD18Y16 motorized spindle was based on the data and Weibull distri-bution to analyze the distribution parameters by modified maximum likelihood function.Finally,the characteristic life of motorized spindle is consistent with the actual value.The results indicate that the method of performance degradation reliability test is reasonable,and the degradation model may re-flect the performance degradation traj ectory.关键词
