套齿联轴器对航空发动机振动特性的影响
Effects of Gear Coupling on Aero-engine Vibration Characteristics
摘要
Abstract
The aero-engine gear coupling stiffness was studied herein ,and the coupling dynamic gearing forces were deduced ,the relationship among the gear coupling gearing forces and the torque , misalignment ,and the dynamic relative displacements was analyzed .According to aero-engine gearing structure characteristics ,a rotor dynamic model including gear coupling and the three supports was es-tablished ,and the effects of gear coupling stiffness on the system frequency response function were an-alyzed;under the conditions of considering the angle misalignment between two rotors ,the effects of gear stiffness on the misalignment responses were studied .The results show that the dynamic gearing stiffness model can simulate the gear coupling dynamic stiffness very correctly ,but the dynamic change range of the stiffness is not enough to change obviously the system dynamic characteristics , however ,the effects of the angle stiffness of gear coupling on the system vibration characteristics are very great .关键词
