| 中文摘要: |
| 基于Abaqus软件对井下矿用17.5R25全钢工程机械子午线轮胎的耐磨性能进行优化。通过有限元方法模拟轮胎的接地印痕，量化表征接地印痕形状，同时引入磨耗能的概念，通过有限元分析计算轮胎模型的磨耗能来量化表征轮胎的耐磨性能。结果表明：轮胎内轮廓的胎肩及肩下部位的曲率半径对轮胎的接印痕形状有显著影响；增大胎肩及肩下部位的曲率半径，可以有效改善轮胎的接地压力分布、优化接地印痕形状，进而提升轮胎的耐磨性能，延长轮胎的使用寿命。采用上述方法可以提高轮胎的抗偏磨性能，缩短轮胎的研发周期，节约开发成本。 |
| 英文摘要: |
| The wear resistance of 17.5R25 all-steel off-the-road radial tire for underground mining was optimized based on Abaqus software.By using finite element method，the grounding footprint was simulated，and the shape of the grounding footprint was quantitatively characterized.At the same time，the concept of wear energy was introduced，and the wear energy of the tire model was calculated through finite element analysis to quantitatively characterize the wear resistance of the tire.The results indicated that，the curvature radius of the shoulder and lower part area of the inner contour of the tire had a significant impact on the shape of the grounding footprint of the tire.Increasing the curvature radius of the shoulder and lower part area could effectively improve the distribution of tire grounding pressure，optimize the shape of grounding footprint，thereby enhancing the wear resistance of the tire and extending its service life.The above method could improve the anti eccentric wear performance of the tire，shorten the development cycle of the tire，and save development cost. |
