The displacement of each mode is determined by a balance between the energy fed into the riser over lock-in regions and the energy dissipated by the fluiddamping over the remainder.
各阶模态的响应位移通过平衡涡激锁定区域内柱体的输入能量与非锁定区内流体阻尼的耗散能量计算得到。

There are three sections of damping force, and they are background damping force of a fluid viscosity, electric damping force of applied electric field and pressure of gas.
With its particular performance, electrorheological fluid can be used as controllable damping media, which bring a promising way to research the semi-active engine mount system.
