基于有限元模拟的极限拉深系数优化

Optimization of limiting drawing coefficient based on finite element analysis

结合0.618优化算法,运用ANSYS分析软件,通过改变坯料尺寸的方法,对板料的成形过程进行模拟,对板材的极限拉深系数进行逼近优化,并将模拟和优化结果与物理拉深试验结果进行了比较。

The paper simulated the blanking formation process, approached and optimized the limiting drawing coefficient of blanking by changing blanking dimension, Integrating 0. 618 optimization algorithm and using ANSYS analysis software. Finally, the result of the simulation and optimization is compared with the result of the drawing test.
