Abstract

Abstract: Based on the characteristics of GH536 super alloy material, the nonlinear rules of change in its thermal physical parameters with temperature is obtained through the test using a numerical method, and the finite element simulation of temperature field distribution of electrical discharge griding (EDG) honeycomb ring is made using ABAQUS, and the effect of temperature field distribution on quality of surface of honeycomb ring is analyzed. The results show that it is feasible to use the finite element analysis to simulate the distribution law of the temperature field in the EDG honeycomb ring, the simulation process is accurate and rapid, and it is also applied to optimize the craft process of EDG related thinwalled parts. It can be also used to provide the theory basis of calculating precisely the thermal stress and residual stress in EDG processing.

Key words: manufacturing process and equipment, ABAQUS, electrical discharge grinding, honeycomb ring, nonlinear thermal physical parameter, temperature field simulation
