| 摘 要： | 以超高分子量聚乙烯的非线性粘弹性性质为基础,将代表非线性、大变形的超弹性 Arruda-Boyce 模型与粘弹性力学模型相结合,建立了超高分子量聚乙烯齿轮的力学模型和几何模型,并将其与 ABAQUS 非线性有限元分析软件相结合,对齿轮的应力分布、变形、承载能力进行分析。结果显示,齿根部位所受的弯曲应力最大,建立在粘弹性基础上的分析结果具有较高的可靠性。

| Abstract: | the nonlinear viscoelasticity model is built up by introducing the Arruda-Boyce model into viscoelasticity model. This Arruda-Boyce model represents hyperelasticity with nonlinear and big deformation. The mechanical model and geometrical model of UHMWPE gears are combined with FEM software ABAQUS. Then the stress distribution, deformation and load capacity are computed. The results show that the peak bending stress is at gear roots , and simulation based on visco-elastic has higher reliability. |
