利用电流变液这种智能材料的物理效应及力学性能 ,根据可控阻尼介质的特殊应用要求 ,研制出一种零电场低粘度且可控粘度变化范围较大的电流变液。并设计制作了一种多层滑动极板式阻尼铰 ,将其用于机翼操纵面的颤振半主动控制 ,使所研究模型的颤振临界速度提高了 36.3%。研究结果表明 ,电流变阻尼器可用于机翼操纵面颤振控制研究中。 According to the physical and mechanical properties of ER material, a kind of ER fluid with low electric field, low viscosity and large changeable range of controllable viscosity was developed according to the special requirements of controllable damping medium. A multi-layer sliding plate-type damping hinge was designed and manufactured for the flutter semi-active control of the wing control surface, which increased the flutter critical speed of the studied model by 36.3%. The results show that the ER damper can be used in the flutter control of wing control surfaces.
