汽车覆盖件冲压方向优化系统设计

Design of Press Direction Optimization System of Automobile Covering Panels

通过分析汽车覆盖件冲压方向选择的影响因素,建立了以评价函数法为基础的冲压方向优化模型。该模型分析了冲压件截面形状,确定所有截面转角的公共可行域,并建立一组目标函数作为优化对象。在公共可行域内优化各个截面的转角,然后加权平均得到目标函数的最优值。最后,编程实现覆盖件冲压方向的优化,并以典型覆盖件为例进行了理论验证。

The paper analyzes the factor influencing the press direction choosing of automobile covering panels, and the optimization model of the press direction is put forward based on the means of the evaluating function. The panel cross section is analyzed in the model, and the feasible zone of all cross section rotating angle is located, and a group of target function is proposed as optimized object. All cross section rotating angle is optimized in the feasible zone, and the optimal value of target function is calculated. Finally, the optimization program of the press direction is designed to examine the theory using the typical covering panel.
