板式阀-插装阀混合的复杂集成块元件布局设计

Components layout design of complex manifold block with both plate valve and cartridge valve

液压集成块外部元件布局设计与内部油路连通设计的强耦合效应是妨碍其实现自动设计的核心问题.系统归纳总结了2类元件布局经验知识,即隐含于各类标准、技术规范与大量工程实例中文档化设计知识,以及专家在长期工程实践中积累的经验知识.在此基础上提出了一种基于知识和规则推理的板式阀-插装阀混用的液压集成块元件布局设计方法.由于布局经验知识与规则综合考虑了后续油路路径规划,元件的安装、调试与维护等方面的需求,因此极大降低了集成块设计的复杂程度.该方法与虚拟设计技术或智能优化算法相结合,为液压集成块的智能优化设计提供了一条有效途径.

The strong coupling effect, which results from external components layout design and internal flow paths connection design, is a crucial issue to prevent the automatic design in hydrau- lic manifold block. The empirical knowledge of components layout was systematically classified as two types： documented knowledge existing in standards, technical specification and engineering design, and expertise accumulated by human experts in long-term engineering practice. And then based on knowledge and rule reasoning, a design methodology for components layout was pro- posed for hydraulic manifold block with both plate valve and cartridge valve. Because the layout empirical knowledge and rules take subsequent path planning, installation, adjustment and main- tenance of components into overall consideration, the design complexity of manifold block was re- duced greatly. The proposed method can be combined with virtual design technology or intelli- gent optimization algorithm to provide an effective approach for intelligent optimum design of hy- draulic manifold block.
