Abstract: To improve the design efficiency and the overall performance of cartridge manifold block,a general structure for CAD system was presented based on the design procedure analysis.For the surface layout problem,a backtracking algorithm based on engineering rules was put forward,by which efficient and correct layout results could be achieved with library features on parameter configuration|for the holes routing problem,a multi-hole routing approach was proposed based on the cooperative co-evolutionary ant colony algorithm.Thus the optimal strategies of holes connecting order were given and all inner holes were optimally connected.A cartridge manifold block CAD system was developed under SolidWorks software,with which the application case of a hydraulic press's ejection cylinder part was used to demonstrate the feasibility of proposed system.

Key words: cartridge manifold block, computer aided design system, layout and holes routing, optimal design

摘要： 为了提高插装阀集成块的设计效率和整体性能,通过分析布局与布孔的设计流程,提出插装阀集成块CAD系统的总体结构。针对表面布局问题,构建了基于工程规则的插装阀块布局回溯算法,结合参数化配置下的库特征可实现集成块的快速正确布局|针对布孔问题,提出一种基于合作型协同进化蚁群算法的集成块多孔道布孔方法,解决了布孔顺序问题,实现了内部孔道连通的优化设计。开发了基于SolidWorks的插装阀集成块CAD系统,结合某液压机顶缸部分插装阀块的设计实例,验证了系统的实用性。
