The invention discloses a lift fan exhaust blade grid vibration reduction method and system, and the method comprises the following steps: S1, obtaining the working state of a lift fan exhaust blade grid; and S2, selecting a preset control quantity according to the working state, and controlling an actuator pre-mounted at the control part to generate an actuating force for reducing or offsetting deformation. The lift fan exhaust blade grid can be damped under the condition that the pneumatic performance of the exhaust blade grid is prevented from being reduced.

    本发明公开了一种升力风扇排气叶栅减振方法及系统,其中该方法包括以下步骤,S1,获取升力风扇排气叶栅的工作状态;S2,根据工作状态,选取预先给定的控制量,控制预先安装在控制部位的作动器产生减小或抵消形变的作动力。本发明能够在避免排气叶栅气动性降低的情况下,对升力风扇排气叶栅进行减振。
