应力-强度干涉模型下的滚动轴承可靠性评估与设计方法
Reliability Evaluation and Design Method of Rolling Bearings Under Stress-strength Interference Model
摘要
Abstract
Aiming at the low reliability and lack of design basis of rolling bearings,a reliability evaluation and design method of rolling bearings under stress-strength interference model was proposed.Considering the random characteristics of the actual equivalent dynamic load and the specified equivalent dynamic load,and assuming that the two random variables subject to lognormal distribution,the reliability evaluation and design model for rolling bearings was established.Secondly,the simulation verification is carried out for the deep groove ball bearings and angular contact ball bearings under multiple models and conditions.The results show that the reliability evaluation and design method of rolling bearing proposed in this paper can make the optimized bearing meet the target reliability life under this working condition by analyzing the allowable range of equivalent dynamic load and combining with the bearing design formula,and achieve the reliability evaluation and design of rolling bearing accurately and effectively.关键词
