运用 ANSYS/ LS-DYNA 软件对复合板应用于汽车保险杠进行了仿真模拟,根据保险杠低速碰撞试验规范-SAEJ2319,把不同厚度比的 PP/低碳钢复合板保险杠与单层的 PP 保险杠和单层低碳钢保险杠的碰撞性能进行对比,分析所得出的变形,加速度,碰撞应力应变,能量等特征参数后发现复合板的碰撞综合性能较好,其中厚度比为2：1的PP/低碳钢复合板碰撞综合性能最好。为 PP/低碳钢复合板运用于汽车保险杠的可能性提供了参考依据。
運用 ANSYS/ LS-DYNA 軟件對複閤闆應用于汽車保險槓進行瞭倣真模擬,根據保險槓低速踫撞試驗規範-SAEJ2319,把不同厚度比的 PP/低碳鋼複閤闆保險槓與單層的 PP 保險槓和單層低碳鋼保險槓的踫撞性能進行對比,分析所得齣的變形,加速度,踫撞應力應變,能量等特徵參數後髮現複閤闆的踫撞綜閤性能較好,其中厚度比為2：1的PP/低碳鋼複閤闆踫撞綜閤性能最好。為 PP/低碳鋼複閤闆運用于汽車保險槓的可能性提供瞭參攷依據。

Using the ANSYS/ LS-DYNA software to simulate a composite plate which is used in automobile bumper. Accord-ing to the bumper collision test specification -SAEJ2319, after comparing the collision performance of different thickness ratio of PP/ low carbon steel composite plate bumper, the single layer of PP bumper and the single layer of low carbon steel bump-er, and analyzing the deformation, the impact acceleration, stress and strain energy and other characteristic parameters, we found that composite plate has a better comprehensive properties. Especially, the thickness ratio is 2:1 PP/ low carbon steel composite plate and has the best collision performance. The result provides a reference basis for the possibility of PP/ low car-bon steel composite plate which can be used in automobile bumper.
