| 摘 要： | 以粘弹性Maxwell模型材料的积分松弛型本构关系为基础，进行了本构关系递推，并建立了Maxwell模型粘弹性体的有限元分析模型，再利用节点对接触模型理论编制了Maxwell模型二维接触问题接触应力计算有限元程度，并验证了其正确性。最后应用该程序，研究了简单Maxwell模型轴对称粘弹性体接触时接触面上轴向应力分布及其变化规律。

| Abstract: | Based on the integral relaxation constitutive relation of Maxwell viscoelastic material,constitutive relation was deduced. The analysis model of finite element was suggested. The program of finite element was developed to study the stress of two dimensions Maxwell viscoelastic bodies on contact by using contact model of node to node,moreover the correctness is validated.Finally,the article calculates the Maxwell model axial symmetry viscoelastic and finds the pressure distribution rules of interface. |
