A coupling dynamic model for whole aero-engine vibration and its verification

  • 摘要: 针对航空发动机整机振动,建立了一种通用的复杂转子-支承-机匣耦合动力学模型.在模型中,利用有限元方法对转子和机匣系统进行建模.支承系统采用集总参数模型,计入了滚动轴承和挤压油膜阻尼器的非线性,定义了多种支承和连接方式,以适应多转子和多机匣的复杂结构建模.运用数值积分获取系统非线性动力学响应.针对两个实际的航空发动机转子实验器,建立了整机耦合动力学模型,进行了整机模态实验验证,结果表明了航空发动机整机振动耦合动力学建模方法的正确有效性.
