摘　　要：基于大型有限元软件ANSYS,对O型橡胶密封件的压缩过程进行模拟,得到压缩应力与压缩量、接触应力与压缩量的关系:压缩量小于15 mm,压缩应力与压缩量呈线性变化,压缩量大于15 mm,压缩应力随压缩量的增加急剧增长;压缩量为13 mm、15 mm、18 mm时,最大接触应力分别为0.41 MPa、0.49 MPa、0.69 MPa。水密性试验证实有限元模拟得出的结果与实测结果基本符合。根据模拟分析与试验结果,对O型橡胶密封件在防水工程上的应用提出了几点建议。Based on the large finite element software ANSYS,compression process of O-shaped rubber seals was simulated,obtaining relationships between compressive stress and value compressed and between contact stress and value compressed.When value compressed is less than 15 mm compressive stress is linear with value compressed and when value compressed is more than 15 mm compressive stress increases sharply as value compressed goes up.When the values compressed are 13 mm,15 mm and 18 mm,the maximum contact stress are 0.41 MPa,0.49 MPa and 0.69 MPa respectively.Watertight test shows that simulation results conform to values measured.By the simulation analysis and test results,the paper makes some suggestions on application of O-shaped rubber seals in waterproofing engineering.
