| 中文摘要: |
| 采用ANSYS软件，分析单段式煤气柜（也称干式威金斯气柜）用橡胶密封膜在实际运行过程中的受力情况以及吊装状态（自重力作用）下的变形情况。结果表明：橡胶密封膜在运行过程的最大应力约为4.3 MPa，出现在厚度为3.3 mm、宽度为300 mm的范围内，橡胶密封膜的最大受力约为4 257 N；高度为30 m的不同覆胶帘布结构橡胶密封膜在自重力作用下的变形均小于其总高的0.5%。 |

| Using ANSYS software，the forces and deformations of the rubber sealing membranes for the single-stage gasholder（also known as dry Wiggins gasholder） during actual operation and lifting（self gravity effect） conditions were analyzed.The results showed that the maximum stress of the rubber sealing membrane during operation condition was about 4.3 MPa，it appeared within the range of thickness of 3.3 mm and width of 300 mm，and the maximun force on the rubber sealing membrane was about 4 257 N.The deformations of the rubber sealing membranes with different coated cord structures and height of 30 m during self gravity effect were less than 0.5% of their total heights. |
