摘要
本文应用传递矩阵法和松弛迭代法,结合具体发动机型号对支承于弹性鼠笼和挤压油膜阻尼器上的高速柔性转子系统稳态不平衡响应进行了理论分析。分析中考虑了轴的质量分布和转子的陀螺力矩。讨论了油膜阻尼器参数、弹性支承刚度系数及不平衡量参数对转子系统稳态不平衡响应的影响,从而为发动机减振系统设计提供了理论依据。
The steady state dynamic unbalance response of a practical model aircraft en-gine supported in a squeeze film damper and a squirrel cage support has been theoretically analyzed using both transfermatrix method and relaxation iteration meth-od.Mass distribtuion of shafts and gyroscopic moment of rotors are taken into accountin the analysis.The influence of stiffness coefficients and unbalance parameters on the dynamicresponse of rotors are investigated,so it can provide the theoretical basis of damping system de-sign of engines.
