摘要
对卷制轴套成形模拟仿真中的常用材料模型作了细致探讨,基于MSC/Marc软件建立了有限元仿真模型,并采用不同材料模型对典型卷制过程进行仿真分析,通过与实际卷制数据的比较分析表明,不同的材料模型所得到仿真结果相对于实际工况而言精度差异是比较明显的,因此进行仿真时必须根据具体情况选择适当的材料模型。为更好的了解轴套在卷制成形时的力学行为和在进行卷制仿真时如何合理地选择材料模型提供了参考。
The generally used material models in formation simulation of wrapped bearing bushes are introduced in detail, and the finite element models are established in this paper based on MSC/Marc software package. The analysis on model simulation is conducted by using different material models. Compared with the data from actual work, it is evident that different material models result in different precisions. Hence, it is necessary to choose a proper material model in accordance with specified requirements, which offers references to the better understanding of mechanics in the wrapped formation and the selection of material models.
