摘要：

以汽车覆盖件冲压材料利用率为研究内容，利用有限元数值模拟方法，确定冲压板料剪裁形状。并提出通过计算面积评价指标值E及成形质量评价指标值s，最终获得板料剪裁尺寸的方法，从而有效提升板料冲压材料利用率。通过对某汽车后端板加强件进行实例分析，材料利用率比原板料尺寸提高5%。此方法为企业降低生产成本提供了一种有效途径。

Taking the stamping material utilization ratio of automobile panel as research content，the clipping-shape of stamping sheet was got using finite element numerical simulation. The clipping-size was acquired eventually by calculating the area of evaluation index E and forming quality evaluation index s, which can improve the material utilization ratio effectively. Through instance analysis of end plate reinforcement of an automobile, the material utilization ratio increased about 5% than that of the original. Therefore, the method is an effective way for enterprises to reduce production costs.
