摘要
介绍了动态显式有限元法的原理、特点和应用,并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。模拟分析的结果说明了动态显式有限元法在模拟像冲压加工这种大变形过程中的优越性。
The principle, characteristic and application of dynamic-explicit FEA are introduced and the simuktion of cold forging the across-bar used in railway vehicle is conducted with dynamic-explicit FE. The simulation proves the advantage of the application of dynamicexplicit FE in large deformation and contact simulations.
