【摘要】：针对深水卡爪式连接器的密封性能,以赫兹理论为基础,建立了透镜式密封的接触力学模型,得出半接触宽度、最大接触应力及压紧力之间的关系,指出透镜式密封圈的球面半径和法兰锥面角度是影响深水卡爪式连接器密封性能的主要结构参数.对深水卡爪式连接器的密封结构进行参数化建模,以最小压紧力为目标函数对其进行了优化,通过敏感性和相关性分析验证了设计参数对密封性能的影响,得到设计最小解.对优化前后的密封结构进行有限元仿真分析,证明优化后的结构可以有效地提高密封性能,最大接触应力增加了37.9%,接触宽度增加了36.0%.建立卡爪式连接器密封性能等效试验模型,对优化前后的密封结构进行静水压力试验,给出了相应的试验结果对比,证明了优化后结构尺寸的正确性和合理性.
[Abstract]:Based on Hertz's theory, the contact mechanics model of lens seal is established for the sealing performance of deep water claw connector. The relationship among half contact width, maximum contact stress and compression force is obtained.It is pointed out that the spherical radius and flange cone angle of lens seal ring are the main structural parameters which affect the sealing performance of deep water claw connector.The sealing structure of deep water claw connector is modeled parameterized and optimized with the minimum compression force as the objective function. The influence of design parameters on seal performance is verified by sensitivity and correlation analysis, and the design minimum solution is obtained.The finite element simulation analysis of the seal structure before and after optimization shows that the optimized structure can effectively improve the sealing performance, the maximum contact stress increases by 37.9 and the contact width increases by 36.0.An equivalent test model for sealing performance of claw connectors was established. The hydrostatic pressure test was carried out on the seal structure before and after optimization. The results of the test were compared, and the correctness and rationality of the optimized structure size were proved.
