| 中文摘要: |
| 分析全钢载重子午线轮胎激光无损检测气泡的产生原因，并提出相应的解决措施。轮胎激光无损检测气泡主要在半成品部件贴合和胎面辊压过程中产生。通过严格控制半成品部件存放条件、提高半成品部件的粘合性能、改进胎面压辊形状、确定适合的胎面辊压工艺参数等措施，成品轮胎的激光无损检测气泡产生率从0.136 5%减小至0.044 3%。 |
| 英文摘要: |
| In this study，the root causes of bubbles of TBR tire which were detected by laser non-destructive test（NDT）were analyzed and corrective actions were proposed.It was found that the bubbles mainly formed during the lamination of semi-finished parts and rolling process of tire tread.The corrective actions were strict control of the storage condition of semi-finished components，increase of the adhesion property of semi-finished parts，improvement of roller shape for the tire tread rolling process，and optimization on the rolling process parameters.The bubble rate of the finished tire decreased from 0.136 5% to 0.044 3%. |
