电液舵机抑制颤振的设计思路

Design ideas on the suppression of flutter of electro-hydraulic actuator

随着导弹性能提升，在飞行中的气动力、弹性力及惯性力耦合作用下，舵系统极可能产生振幅不衰减的自激振动（即气动颤振），如何抑制颤振发生是目前摆在舵机研究中比较迫切的问题，阐述了电液舵机抑制颤振发生的设计思路。

With the improvement of missile performance, it is highly likely for the actuator system to generate the self-excitation without amplitude attenuation, that is, aerodynamic flutter, under the coupling action of aerodynamic force, elastic force and inertial force. Therefore, how to suppress the flutter is a pressing problem in the study of actuator. The design ideas on suppression of flutter of electro-hydraulic actuator is presented.
