Liquid Inertia Damper that Utilizes Electromotive Induction for Passive and Active Vibration Control Device

研制了一种利用电流体的电动势感应的液体惯性阻尼器，它既可用于被动式振动控制装置，也可用于主动式振动控制装置。阻尼器有一个充满盐水的长旁通管，旁通管上有电节点和磁节点，电磁铁安装在旁通管周围。试验结果表明，液体在高压强磁场下可以运动，在8个电磁节点切换下，试验阻尼器的阻力可以通过Fleming相互作用来控制。

An liquid inertia damper that utilizes electromotive induction of electrically fluid applying for not only passive and also active type vibration control device is developed. Damper has a long by-pass pipe filled in salty water with electric node and magnetic node, and electromagnets are installed around the by-pass pipe. It is obvious from test results that the liquid can move under high voltage and high magnetic field, and resisting force of the test damper are controllable by the Fleming interaction under switching eight electromagnetic nodes.
