| 中文摘要: |
| 针对盾构机主驱动超大聚氨酯（PU）密封圈（简称PU密封圈）在生产及应用中存在的问题，利用有限元分析软件Ansys对PU密封圈结构进行仿真优化；研究了主要原材料对PU弹性体性能的影响；进一步对PU密封圈的生产环境、配套设备和工艺以及产品评测平台进行优化设计，形成了整套自动化连续硫化生产技术，确保了盾构机主驱动PU密封圈的质量稳定性和在实际工程中良好的应用效果。 |
| 英文摘要: |
| Aiming at the problems existing in the production and application of the main drive superlarge
polyurethane（PU） sealing ring（PU sealing ring for short） of shield machine，the structure of the
main drive PU sealing ring of shield machine was simulated and optimized using the finite element analysis
software Ansys. The influence of main raw materials on the properties of PU elastomer was studied，the
production environment，supporting equipment，process and product evaluation platform of the main drive
PU sealing ring of shield machine were optimized，and a complete set of automatic continuous vulcanization
production technology was established，which ensured the quality stability of the main drive PU sealing ring
of shield machine and its good application effect in practical engineering. |
