基于约束网络的高速列车车体关联设计技术研究

Research on High-Speed Train Car Body Associated Design Based on Constraint Network

针对现有高速列车车体缺乏对多样化、个性化需求快速响应设计方法的研究,采用Top-down设计思想,提出一种基于约束网络的高速列车车体关联设计方法。通过关联设计实现装配信息变更影响在车体多层级骨架模型中自顶向下自动传递,并建立约束网络模型关联产品功能、性能、结构等多域特征信息,实现需求驱动的高速列车车体快速设计。以某车体侧墙模块设计为例,验证了该方法不但实现需求驱动的车体快速设计,而且通过建立显式的多域特征信息影响传播机制,保证多域特征参数变更设计的正确性。

In consideration of the problem of the lack of the rapid design method of high-speed train car body to response customer＇s diversified and individual demands, an approach by combining the top-down design philosophy with the constraint network is used to study the associated design method of the high-speed train car body in this paper. The alterations of assembly information can be transmit automatically from multi-level skeleton model of car body based on associated design technique is provided. Besides, the multi-field feature information such as product function, performance and structure could be associated by the constraint network, and then designers can depend on it to implement the demand-driven rapid design of high-speed train car body. Finally, in a car body sidewall module design as an example to validate the method can not only achieve demand--driven rapid design of high-speed train car body, and through establishing explicit multi-domain feature information dissemination mechanism, guarantee the correctness of the multi-domain feature parameters change design.
