Abstract


To verify the existence of complex castings residual stress problems, this paper established a software UG gearbox housing simulation model, using ANSYS software to simulate the gearbox housing , through simulation of complex castings molding process , in which there is residual internal verification stress . To study and solve the heat treatment process parameters conditions on residual stress effects , we use ANSYS software to simulate different conditions gearbox housing the heat treatment process. Through a comparative study of different materials at the same temperature , the same cooling rate on complex castings internal residual stress effects ; same material , different temperatures , different cooling rates on complex castings internal residual stress effects , to arrive at a reasonable process parameters , making the complex casting residual stress with minimal impact . Using the general parameters simulated residual stress compared to the actual distribution , the heat treatment process parameters derived internal residual stress and casting the relationship between existence . To do with the theory of heat treatment and compared to further validate the correctness of the theory .
