Numerical simulation and parameter optimization of seal property of bidirectional rotating cylinder gas film

  • 摘要: 在对气膜密封结构及性能分析的基础上,提出了双向旋转倒斜T字型与双层斜槽型柱面气膜密封界面结构;建立了2种结构密封气膜的数理模型和基于有限元方法的密封气膜数值分析模型;在VC平台上开发了基于有限元计算的密封气膜压力分布、系统密封特性及槽型结构多维参数优化的计算分析程序,实现了对密封气膜压力分布、密封特性的数值计算及结构参数的优化设计;在Gambit中建立了不同平均膜厚下倒斜T字型柱面气膜的物理模型和有限元分析模型,通过FLUENT进行了密封气膜特性数值仿真,商用软件仿真结果与自主开发程序数值计算结果对比一致性好,验证了开发程序的正确性;计算对比了2种界面结构的密封稳态特性与动态特性,在相同计算参数下,倒斜T字型的密封性能优于双层斜槽型,为密封系统设计选型提供了帮助;基于遗传思想的粒子群多维优化(GAPSO)计算程序的开发,为槽型参数的优化设计提供了有效的手段。
