摘　　要：通过介绍高强钢,重点分析了L42F车型中高强钢零件仪表板下段的成形特点,并经过工艺试验和计算机仿真技术相结合的方法,找到该零件初期生产开裂的主要因素。通过提高钢材加工硬化系数(即N值),解决了拉深胀形开裂的问题,实现了批量生产。The definition of high strength steel was introduced in this paper,and the forming characteristics of DASH LWR LHD made of high strength steel in L42F were analyzed especially.Then the key factor causing crack of the part was analyzed and the corresponding improvement measures were found through the combination of test and simulation.By improving the work hardening coefficient（namely N value）,crack of the part in drawing and bulging can be eliminated,and mass production can be realized.
