摘要
通过交叉杆材料的拉伸实验,获得了交叉杆材料的应力—应变关系;在此基础上,用动态显式有限元法对机车车辆的转向架交叉杆冷冲压加工过程进行计算机模拟分析。在不同工艺参数下,如:不同的摩擦系数、不同的冲压速度等,对冲压过程中应力、应变和局部减薄量等进行了分析。模拟结果为减少调试和优化工艺参数提供了依据。
Based upon stress-stra in relation obtained via extension test of material of crossing rod,computer simu la-tion on cold forgiing process of crossing rod of revolving support of locomo tive vehicle has been done using dynamic indicated FE method.Stress,strain and local reduction of thickness in forging process with variety of technological p arameters such as friction coefficient,forging speed has been analysed.Results of simulation can be referrence to reduction of adjustment and optimizing tech nological parameters.
