自动装填机构刚度混合全局灵敏度分析
Combined global sensitivity analysis for stiffness of automatic loading mechanism
摘要
Abstract
In order to identify the important parameters and key parameters affecting the stiffness of the automatic loading mechanism, a combined global sensitivity analysis method is proposed here. The important parameters are identified by the quasi-optimized Morris trajectory based the elementary effect method and then these parameters are identified as the design variables. The key parameters are identified by the global sensitivity analysis method based on the polynomial chaos expansion. Two test functions are given to verify the effectiveness of the proposed method. Finally,the 10 important parameters affecting the stiffness of the automatic loading mechanism are extracted from all the 32 parameters,and the 6 key parameters affecting the stiffness are extracted from the 10 important parameters.关键词
