摘要
针对气密封检测工具胶筒在大变形下的接触密封问题,以31/2"气密封检测工具胶筒为研究对象,分别采用网格重构、自动稳定和准静态分析三种分析方法,模拟了工具胶筒在50MPa载荷下的接触密封情况,并设计正交试验,通过极差分析得出了胶筒的最佳结构参数组合。研究表明,对于橡胶的大变形分析,网格重构法的计算结果较准确,胶筒尺寸参数对胶筒外侧接触应力最大值的影响顺序为:外径>内径>高度,最优尺寸组合为外径72mm、内径36mm、高度120mm。研究成果对应用有限元软件求解橡胶大变形工况下的密封性能和胶筒结构设计具有重要参考价值。
Detection tools for gas seal glue tube contact seal under large deformation problems, with 31/2"gas seal detection tools rubber tube as the research object, with mesh reconstruction, automatic stabilization and quasi static analysis of three methods of analysis, the simulation tool rubber tube in the contact seal condition of 50 MPa load, and the orthogonal experiment design, through the analysis of the poor best glue tube structure parameters combination is obtained. The results show that for the analysis of large deformation of rubber, the calculationresults of mesh reconstruction method are more accurate. The order of influence of the size parameters of packing element on the maximum contact stress on the outside of packing element is as follows: outer diameter >, inner diameter > height, and the optimal size combination is outer diameter 72 mm, inner diameter 36 mm and height 120 mm. The research results have important reference value for the application of finite element software to solve the sealing performance of rubber under the condition of large deformation and the structural design of packing element.
