复杂产品设计指标分解动态演化关联定量分析方法
Dynamic Evolution Correlation Quantitative Analysis Method of Complex Product Design Specification Decomposition
摘要
Abstract
Aiming at the problems that the complex interaction relationship in the evolution processes of the complex product design specification often caused the module design parameters to be overestimated or underestimated,which led to repeated iteration of design,a method was proposed for quantitatively ana-lyzing the interaction relationship in the dynamic evolution processes of the design specifications.Firstly,based on the design structure matrix,combined with regression analysis and grey entropy correlation degree calculation method,the calculation model of design specification coupling correlation strength was con-structed,and the multiple coupling relationship of design specification decomposition was quantitatively analyzed.Then,the theory of community ecology was introduced,and based on Lotka-Volterra model,a quantitative analysis method of dynamic evolution correlation of design specification decomposition was pro-posed to characterize the interaction relationship in the processes of design specification decomposition.By further integrating the quantitative analysis results of coupling correlation and evolution correlation of design specification decomposition,the quantitative analysis of dynamic evolution correlation relationship of com-plex product design specification decomposition was realized.Finally,taking the axle load and braking ca-pacity specification decomposition of a high-speed train bogie as an example,the feasibility and effective-ness of the method were verified.关键词
