区间参数灵敏度分析及其在弹射机构故障树中的应用研究
Study on Interval Parameter Sensitivity Analysis and Its Application to Fault Tree of Ejection Mechanism
摘要
Abstract
Sensitivity analysis can help designers avoid wasting computing resources on factors that have little or no impact in optimization design.Interval sensitivity analysis is a common sensitivity analysis method under the lack of information.This paper studies the importance measurement index that reflects the influence degree of input variables on the change of output value when they change in the interval,discusses its advantages,and puts forward the sensitivity analysis of the index to local parameters.Based on the measure and sensitivity analysis index,the application research is carried out on the numerical example and an ejection system fault tree engineering example,which verifies the practical significance of the measurement and sensitivity analysis.The research in this paper can provide an effective tool for sensitivity analysis when the amount of information is scarce in practical engineering problems.关键词
