The conventional semi-active variable damping (VD) device can only dissipate the vibration energy, which inherently limits its performance in vibration control. This paper proposes a novel semi-active inerter concept and develops a prototype with magnetorheological (MR) dampers, which can store the vibration energy in a flywheel and then release it to suppress vibration. The new idea is inspired by a variable inertance (VI) device, which has a VD device and a passive inerter in serial, and a passive mechanical motion rectifier (MMR), which can convert the reciprocating input into a unidirectional output. The controllable MMR (CMMR) applies two VD devices to replace the two one-way roller clutches in the MMR. By equipping the CMMR, the semi-active inerter gets more controllability than the original VI device because it can switch the torque and motion transmitting routes between the device terminals and the flywheel in it. The frequency-domain analysis validates the versatile of ...

基于可控机械运动整流器的半主动磁流变惰性器，用于振动控制

常规的半主动可变阻尼（VD）设备只能耗散振动能量，这固有地限制了其在振动控制方面的性能。本文提出了一种新颖的半主动惰轮概念，并开发了带有磁流变（MR）阻尼器的原型，该原型可以将振动能量存储在飞轮中，然后释放飞轮以抑制振动。这个新想法的灵感来自可变惯性（VI）设备，该设备具有一个VD设备和一个串联的无源惯性惰轮，以及一个无源机械运动整流器（MMR），该整流器可以将往复输入转换为单向输出。可控MMR（CMMR）应用了两个VD设备来替换MMR中的两个单向滚子离合器。通过配备CMMR，半主动式惰轮比原始VI装置具有更好的可控制性，因为它可以在装置端子和飞轮之间切换扭矩和运动传递路径。频域分析验证了...
