| 中文摘要: |
| 以一款悬架筒式减震器橡胶衬套为例，应用非线性有限元分析软件ABAQUS计算其各向刚度和拉脱力，并与测试值进行对比。计算结果与测试数据吻合证明了分析方法的有效性。另外，还计算和分析了缩径对橡胶衬套各向刚度的影响。结果表明，随着过盈量的增大，橡胶衬套的径向和偏摆刚度显著提高，轴向刚度缓慢降低，扭转刚度基本不变。 |

| Based on the rubber bushing for shock absorber，the stiffness in each direction and pull-out force were calculated with nonlinear finite element software ABAQUS.The calculated results were in good agreement with the experimental results，which demonstrated the analysis method was reliable and effective.In addition，the influence of magnitude of interference on the stiffness of the rubber bushing in each direction was analyzed.The results showed that，with the increase of magnitude of interference，the radial and yaw stiffness of the rubber bushing increased significantly，the axial stiffness decreased slowly，and the tensional stiffness remained about the same. |
