摆动负载
振动负载
振动荷载

This thesis , which is devoted to the research on the smart rotor with actively controlled trailing - edge flap for hub oscillatory load reduction , offers a potential approach for the vibration reduction of helicopter
本文对带有主动控制后缘附翼的智能旋翼用于降低桨毂交变载荷进行探索性的研究，为降低直升机飞行中机体振动水平提供一条有效的新途径。
Because of the periodicity of the hub oscillatory load and the nonlinearity of the i / o relationship of the smart rotor , the neural control methods with both off - line and on - line modeling in frequency domain on the smart rotor and their realization procedures are presented
飞行中直升机的桨毂交变载荷以周期性的为主，而智能旋翼的输入输出关系具有非线性特征。据此，本文提出离线建模的和在线建模的智能旋翼频域神经控制方法，并给出实现的具体方案细节。
