摘要
为提高高速列车动力学参数设计效率,研究了一种基于知识的参数设计方法。该方法以知识规则库、动力学模型实例为基础,从性能空间到设计空间的映射关系为导向,结合参数化建模、动力学仿真技术,进行动力学参数设计。帮助设计者快速地缩小设计参数集,获取与设计要求相匹配的动力学参数,提高设计效率,缩短周期。最后开发了基于知识的高速列车动力学参数设计系统。
To improve the efficiency of high-speed train dynamic parameters＇ design,a design method based on knowledge was studied. It is based on the knowledge rules and dynamic models,and sets the mapping relationship from the performance space to design space as the guidance. At the same time,it combines the technology of parametric modeling with the dynamic simulation to complete the dynamic parameters＇ design. Following the method can help designers decrease the design scopes quickly and obtain the dynamic parameters to match the design requirements.Thus,it improves the design efficiency and shortens the cycle. Finally a knowledge-driven design system for high-speed train dynamic parameters is developed.
