【摘要】：针对具有参数漂移特征的产品,推导了性能指标退化模型的失效率函数,从理论推导和定性分析两个角度对退化模型的失效率函数进行了深入分析,研究结果表明,退化产品失效率与Gamma型产品具有一定的相似性,能够使用冲击理论直接解释退化产品失效问题。进一步,给出了Gamma分布的参数确定方法,从而可以利用常见寿命分布制定退化产品维修策略。最后通过对液力耦合器的测量数据进行分析,说明所提方法的合理性。
[Abstract]:In view of the parameter drift characteristics of the products, derived performance degradation failure rate function model, from theoretical analysis and qualitative analysis of two aspects of the in-depth analysis of the failure rate function degradation model, the results show that the failure rate of degradation products and Gamma products have a certain degree of similarity, can be used directly to explain the impact theory the degradation products of failure. Further, given the method of determining the parameters of Gamma distribution, which can be used to develop common life distribution of degradation products maintenance strategy. By the end of the hydraulic coupler measurement data are analyzed, the rationality of the proposed approach.
