摘　　要：采用Mooney-Rivlin模型对核电设备人员闸门双道O型密封圈密封结构进行有限元分析,模拟密封圈在不同压缩量情况下的von Mises应力和接触应力,同时通过制造试验台架对其密封性能进行了验证。结果表明,O型密封圈在不同压缩量情况下与密封槽之间的最大接触应力均大于最大von Mises应力;压缩率大于2%(压缩量0.3 mm)时可确保密封效果,但在考虑制造公差及安全裕量后,压缩量最终取值1.6 mm(压缩率10.67%)。台架试验验证了双道O型密封结构的合理有效性。The Mooney-Rivlin model was used to perform finite element analysis of sealing structure of double-channel O-ring seal for personnel airlock in nuclear power plant,the von Mises stress and contact stress of the O-ring seal at different compression size were simulated,and the sealing performance was verified through a test stand.The results showed that the maximum contact stress between the O-ring and sealing groove was greater than the maximum von Mises stress at different compression size.The sea-ling effect could be achieved when the compression rate was greater than 2%(compression size 0.3 mm).However,the O-ring compression rate took compression size the value of 1.6 mm(compression rate 10.67%)after considering the manufacturing tole-rances and safety margins.The test of stand verified rationality and effectiveness of the double-channel O-ring sealing structure.
