| 中文摘要: |
| 通过对国内外多种规格子午线轮胎耐久试验后的破坏断面进行分类整理，总结了子午线轮胎耐久试验后的破坏规律。利用哈尔滨工业大学开发的轮胎专用三维非线性有限元分析软件，分别从最大剪切应变、等价应力、等价应变、应变能密度几个方面对胎肩脱层和胎圈脱层的现象进行了初步的机理分析，从外因和内因两方面指出了提高轮胎耐久性能的方向。 |
| 英文摘要: |
| Based on the analysis of the failed cross-sections for radial tires in many sizes after endurance test, the failure pattern of radial tire in endurance test has been summarized. The mechanism of shoulder and bead seperations is primarily analysed in terms of the maximum shear strain, equal value stress, equal value strain and strain energy density with a 3D non-linear FEA analysis software special for tire developed by Haerbin University of Technology, and the potential measures for improving the endurance are proposed. |
