Abstract: In order to realize parametric design of mining and conveying equipment parts in Web pages quickly and easily, parametric design system of mining and conveying equipment parts based on Web was developed by use of secondary development technology of ANSYS software and Web page design and development technology, and overall design and key technologies of the system were introduced. The system combines parts parameters entered by user in Web page with parts modeling APDL command flow, and call ANSYS software to complete parametric design of mining and conveying equipment parts, so as to reduce professional requirement of designer and improve design efficiency.
