摘　　要：随着往复泵朝着大型化、超高压方向发展,为消除往复泵曲轴设计与强度校核中工作量大、过程繁琐、易出错等弊端,利用ObjectARX,APDL等二次开发工具以及基础类库MFC、ADO数据库接口、曲线离散技术、图表数字化技术等在VC++6.0上开发出一个运行在AutoCAD平台上的动态链接库应用程序,实现了曲轴设计、强度校核、ANSYS的启动调用、曲轴有限元分析的自动化与参数化绘图.对国内外4台往复泵机组曲轴的实例校核表明,程序在解决往复泵机组扩容计算、缺陷曲轴的改造、中外机组曲轴对比分析、提高往复泵曲轴设计效率等方面具有很好的应用.In order to raise the design level of reciprocating pump, and to slove the problems such as large amount of work, complicated process, and making mistakes easily in crankshaft design and strength checking, a DLL application program was developed on VC ＋ ＋6.0 and run on AutoCAD by using ObjectARX, APDL, MFC, ADO, and technologies such as discrete curve and graph digitizing. In this program, such tasks as designing, drawing 3D models by parameterization, strength checking and FEM to crankshaft could be fulfilled. The results and data indicate that the program can enlarge the capability of pump unit, modify the defects in crankshafts, select the most favorable alternatives to crankshafts, and increase design efficiency.
