摘要
为了更好地了解和掌握某型航空发动机转子系统固有的振动特性及不对中状态下振动特性变化趋势,对正常和平行不对中状态下的该型航空发动机双转子系统进行了模态分析,分别计算了各自前6阶固有频率,并对仿真结果进行了对比分析.研究工作可为该型航空发动机的优化运行及其双转子结构优化设计提供参考和依据.
In order to better understand and master the inherent vibration characteristics of an aero-engine and the variation trend of the vibration characteristics in misalignment state,the modal analysis of the dual rotor system of the aero-engine under normal and parallel misalignment conditions was carried out,the natural frequencies of the first 6 orders were calculated respectively,and the simulation results were compared and analyzed. The research work provides a reference and basis for the optimized operation of the aero-engine and the optimization design of its dual-rotor structure.
