| 中文摘要: |
| 对12R22.5无内胎全钢载重子午线轮胎胎圈结构进行优化设计，并利用Abaqus软件建立轮胎有限元模型对不同设计方案进行对比分析。有限元分析结果表明，硬三角胶端点到钢丝圈内端点距离为37 mm的S7方案轮胎的充气外缘尺寸符合国家标准要求，且胎圈损坏区域、帘布端点和胎肩带束层端点应变能密度较小，为优化方案。成品轮胎胎圈耐久性试验结果表明，S7方案轮胎胎圈耐久性能优于原生产轮胎，与有限元分析结果一致。 |
| 英文摘要: |
| The design of bead structure of 12R22.5 tubeless truck and bus radial tire was optimized,and different designs were analyzed comparatively by using tire finite element model built based on Abaqus software.The finite element analysis results showed that，S7 program was the optimized design,in which the distance between the end of hard bead filler and the inner tip of bead ring was 37 mm.The inflated overall dimensions of S7 program tire met the requirement of national standards,and the strain energy density of damaged area on bead,carcass endpoint and belt endpoint was small.The results of bead endurance test showed that,the bead endurance of S7 program tire was superior to the original tire,which was consistent with the FEA result. |
