摘　　要：采用数值模拟方法研究了法兰结构参数对双楔角环垫密封接触压力及有效密封宽度的影响,并通过正交实验法对法兰结构参数进行了显著性分析.结果表明,随法兰各结构尺寸减小,双楔角环垫主、从密封面最大接触压力不同程度增大.法兰结构参数对新型双楔角环垫密封性能影响的显著性顺序为主法兰小端外径>法兰外径>锥颈大端厚度>锥颈高度>法兰有效厚度.主法兰小端外径对双楔角环垫主、从密封面最大接触压力影响最大.The flange structure parameters which influenced the contact pressure and effective sealing width of ring gasket were analyzed by numerical simulation method. The significance analysis on the flange structure parameters was done by orthogonal test method. The results showed that the maximum contact pressure of the male-female surfaces of the ring gasket increased with the decreasing the flange structure sizes. The significant influence sequence of the flange structure parameters to the key indexes is as follow： male flange outer end diameter〉flange outside diameter〉neck thickness〉neck height〉flange effective thickness. And the outer end diameter of the male flange had the greatest influence on the maximum contact pressure of the male-female surface of the ring gasket.
