Abstract 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.
