摘要
本文采取摄动法对某直升机动力/传动/旋翼(尾桨)机械扭振系统进行了参数敏感性分析,并提出了扭振调频的指导性意见。
It is described that some helicopter engine/drive train/rotor(tail rotor) torsional oscillation parameter sensibility is studied by using perturbance method. A guiding suggestion about frequency modulation of torsional oscillation is made.
