摘　　要：采用B/S和C/S混合结构,将JSP,Servlet技术与商用CAD系统的二次开发技术相结合,构建了房车制动器CAD系统.系统具有支持制动器的结构参数优化、稳健设计、虚拟试验、虚拟装配等功能.给出了系统的框架结构,对组成系统的各个功能模块进行了详细介绍.运用制动器与整车性能的匹配理论,对制动器进行选型分析,给出了整车匹配模块的算法流程图;以制动效能为目标,建立了制动器优化设计数学模型,确定了制动器的主要结构参数.将基于损失模型的稳健设计方法应用于制动器的设计,将基于响应面模型的稳健设计方法应用于电磁体的设计,提高了制动器设计质量;为实现电磁体表面均匀磨损和抗旋转趋势,提出了非对称结构电磁体的优化设计方案.By combining the technologies of JSP and Servlet with secondary development of business CAD system, a CAD system in trailer brake based on B/S and C/S hybrid mode has been built. The system has the functions as optimal design of structure parameter, robust design, virtual testing, and virtual assembly in designing the brake. The frame structure and function modules of the system are discussed in detail. The matching technology of trailer train brake system is introduced in the type selection and brake analysis. The flow chart of the vehicle matching module of the system is given. Taking the braking efficiency as optimum goal, the structure parameters for optimization and the mathematic model of the drum brake are obtained. The optimum design plan of unsymmetrical structures is proposed to realize the even wear of the electromagnet surface and to decrease the revolving tendency.
