Optimization of Hot Stamping Cooling Channel Based on APDL

以汽车防撞梁零件为例,结合传热学与冲压成形相关理论,运用ANSYS进行热冲压冷却过程的仿真模拟,用上、下模具各个流道中心位置横纵坐标、流道半径等参数建立目标函数,利用APDL参数化设计方法对流道进行优化,计算求解出函数的最优解.优化前后的数值模拟结果对比表明,优化后成形件的温度分布更加均匀、应力分布情况得到改善,产品质量得到提高.

Die closing cooling is considered hugely important to hot stamping process,which affects the final product performance.Based on the theory of heat transfer and stamping forming,ANSYS is used to simulate the cooling process of automobile anti-collision beams.The horizontal and vertical coordinates of the center position and the radius of the runner are taken as research objects to establish the objective function.APDL parametric design method is used to optimize the runner,and optimal solution of the function is then calculated.The temperature uniformity of the part is improved,and the cooling effect is significantly increased.
