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 analyzing 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 constructed, 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 proposed 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 complex product design specification decomposition was realized. Finally, taking the axle load and braking capacity specification decomposition of a high-speed train bogie as an example, the feasibility and effectiveness of the method were verified.

摘要:

针对复杂产品设计指标演化过程中的复杂相互作用关系往往会使模块设计参数被高估或低估而导致设计反复迭代的问题,提出一种定量分析设计指标动态演化过程中的相互作用关系的方法。首先,以设计结构矩阵为基础,结合回归分析和灰熵关联度计算方法构建了设计指标耦合关联强度的计算模型,定量分析了设计指标分解的多重耦合关系;然后,引入群落生态学理论,提出了基于Lotka-Volterra模型的设计指标分解动态演化关联定量分析方法,表征设计指标分解过程中的相互作用关系,通过融合设计指标分解的耦合关联与演化关联定量分析结果来实现复杂产品设计指标分解动态演化关联关系的定量分析;最后,以高速列车转向架轴重和制动能力指标分解为例,验证了所提方法的可行性和有效性。
