中文摘要：以B210P1(一种加磷高强度冷轧、无间隙原子高强度钢)、B280VK(一种碳素冷连轧、双相钢钢板)高强度钢板为研究对象，采用物理试验与数值模拟相结合的方法研究了主要力学性能参数(σs、 K、n、 r)对材料拉深成形性能的影响。对比物理模拟和数值模拟：对于拉伸试验所得到的材料性能参数，采用ETA/DYNAFORM软件进行数值模拟试验能有效预测材料的拉深成形性能。
英文摘要：In order to know the drawing formability of B210P1(a kind of cold-rolled plus phosphorus, high strength interstitial free steel) and B280VK (a kind of cold rolling of carbon, dual phase steel plate) high-strength sheet steel, the numerical simulation and physical simulation tests were carried out, the influences of mechanical property parameters (σs , K, n, r) on the drawing formability of B210P1 and B280VK steel sheet were studied. Comparing physical simulation with numerical simulation, it is proved that numerical simulation test using ETA/DYNAFORM software can effectively predict the drawing formability of the material by tensile test.
