基于依赖分析网络的汽车转向轻便性研究

摘要

This paper uses the dependence analysis network to analyze the relationship between the steering portability and structural design parameters,gives out the dependence network model of the automobile steering portability and its simplified model to obtain the qualitative relation between design parameters and the target performance and the qualitative dependence sensitivity and establishes the search model tree to implement the conflict resolution,in order to obtain the best design scheme.The reference basis is provided for steering portability system design.%应用了依赖分析网络,分析研究了转向轻便性与结构设计参数之间的关系,给出了汽车转向轻便性的依赖网络模型及其简化模型,得到了设计参数与性能目标之间的定性关系及定量依赖的灵敏度,建立了搜索模型树,实现了冲突的消解,获得了最佳设计修改方案,为实现转向轻便系统设计提供了参考依据.
