Computer Aided Design System Of Hydraulic Cylinder

Based on the ES(Expert System)and modern design methods such as FEM(Finite Element Method), structural optimization etc., a set of software about the CAD(Computer Aided Design) of hydraulic cylinder for hydraulic press is developed. The software can be used on the platform of AutoCAl) R14 on any PC (Personal Computer) whose operating system is Windows 95,98 or NT .It includes three main modules. One is ES ,named YYGES in this essay. Another is structural optimization, which is also called YKJU5.O. The third is parametric plot. The YYGES comes from the knowledge and experience of experts on hydraulic cylinder. It has intelligence and can offer help during design. Designer can understand the procedure well through the good interface of YYGES. YKJU5.O adopts the complex method as its optimizing arithmetic and FEM as its structure analyzing method. Parametric plot module is an application developed on AutoCAD R14 platform with ObjectARX language. Its UI (User Interface) made by MFC (Microsoft Foundation Class) has the style of Windows and is very friendly. It can make the design easy and is suitable for popularization. Just input some basic parameters of the hydraulic cylinder, and the whole set of drawing will be provided. This software can shorten the design period and improve design at the same time. It has been put into use in factories and got a good favour.
