轮毂轴承有限元分析模型英文文献和中文翻译(3)
The model is composed of one or two artificial planes of symmetry and a part of material defined by them. The model is based on the assumption that plastic deformation is concentrated on relatively small contact area. The model was employed for simulating a cold rotary forging process of a wheel hub bearing assembly, after local contact area was checked quite small, which is a typical application example of the proposed analysis model. The simulation was conducted using a rigid-plastic finite element method assisted by an intelligent remeshing technique. Three cases of 30°, 60° and 90° analysis models were studied to validate the present finite element analysis model. The predictions at their planes of symmetry and mid-planes were investigated and compared with the experiments, revealing that the predictions at the mid-planes are in good agreement with the experiments for all the cases while those at the planes of symmetry are more or less different from the actual phenomena. Based on the discussion about the predictions, the 60° analysis model is recommended for both computational efficiency and solution reliability. With the present finite element analysis model, computational time could be reduced drastically. Acknowledgement This work was financially supported by the BK 21 plus project. References Cho, J.

摘要在本文中，一种用于装配车轮轮毂轴承组件的旋转锻造过程的计算效率的有限元分析模型。分析模型是由材料由两个对称的人工平面定义的一部分，以减少计算时间，在模拟过程中采取整体。三例30°，60°和90°的分析模型旋转锻造工艺模拟研究验证了有限元分析模型。在对称中面的预测进行了研究和实验比较，表明在中平面的预测是在所有情况下的实验结果一致而在对称平面是相反的。因此，60°分析模型被推广用于计算效率和解决方案的可靠性。与现有的有限元分析模型，一个小时的电脑计算时间可以足够获得这样的旋转锻造过程中的有价值的信息作为轮毂轴承组件的制作过程。论文网
