Reliability Assessment Based on Physical Parameters

doi:10.3969/j.issn.1000-1093.2015.06.020

Abstract

Abstract: A scientific evaluation method used to evaluate mission reliability is difficult to get enough failure data in limited testing time for the large mechanical equipment, or even get no failure data. Reliability assessment based on physical parameters has become an effective way. The reliability assessment process based on physical parameters is briefly described. The system nonlinear correlation analysis method based on the Kendall correlation coefficient and the relation between input and output variables based on kernel regression modeling method are discussed. The output parameters of the conditional probability distribution theory based on kernel regression and device reliability evaluation methods are given. A large complex mechanical hydraulic equipment is evaluated, which monitors the performance parameters in order to use the reliability calculation method to achieve the mission reliability assessment.

Key words: mathematical statistics, reliability evaluation, physical parameter, Kendall correlation analysis, kernel regression modeling
