Synchronous Optimization Design of Fixture Layout and Clamping Force Based on UG

摘要

In order to improve the accuracy and design efficiency of fixture, UG and ADMAS software has been introduced into the fixture design process, and the co-simulation function of software has been applied, and the fixture reasonable layout and the clamping force calculation and synchronous optimization has been realized. The fixture is carried out in the UG software, by using the machining process of the workpiece, and the fixture is fully opened by the addition of the motion constraint. The dynamics simulation is carried out by introducing UG fixture model into ADMAS software, and the sensitivity of the key points of the spring clamping force is obtained by calculating, the points that having greater impact on the spring clamping force is optimized, and the spring displacement of the variable point when the spring produces the maximum clamping force is obtained, so as to realize the fixture optimization design.
