Active and semi-active viscous fluid damper and control method thereof
The invention belongs to the technical field of hydraulic dampers, and particularly relates to an active and semi-active viscous fluid damper and a control method thereof. Comprising a cylinder, a piston rod and a piston, the piston rod penetrates through the fluid space of the cylinder barrel and is in sealing contact with the cylinder barrel in a linear displacement manner; the piston is installed on the piston rod and divides a fluid space of the cylinder barrel into a first cavity and a second cavity in the displacement direction of the piston rod, the first cavity and the second cavity are communicated through a damping channel in the cylinder barrel and bypass damping holes, and the bypass damping holes comprise the first damping hole and the second damping hole which are formed in the two opposite ends of the cylinder barrel respectively. The first damping hole and the second damping hole are connected with the compensation oil way to form a pressure adjusting loop. The control method comprises the steps that when actual vibration of the structure to be subjected to vibration reduction exceeds the vibration limit value, the compensation oil way starts to work, and active control force is applied; and when the actual vibration of the to-be-damped structure is lower than the vibration limit value of the to-be-damped structure, the compensation oil way stops working, and semi-active control force is applied.
本发明属于液压阻尼器技术领域，具体涉及一种主动、半主动粘滞流体阻尼器及其控制方法；包括缸筒、活塞杆和活塞；活塞杆穿过缸筒的流体空间以可直线位移的方式与缸筒密封接触；活塞安装在活塞杆上将缸筒的流体空间沿活塞杆位移方向分隔为第一腔体和第二腔体，第一腔体和第二腔体通过缸筒内的阻尼通道和旁通阻尼孔导通，旁通阻尼孔包括分别设置于缸筒两相对端的第一阻尼孔和第二阻尼孔，第一阻尼孔和第二阻尼孔分别与补偿油路连接形成压力调节回路；控制方法是，当待减振结构实际发生振动超过其振动限值时，补偿油路开始工作，施加主动控制力；当待减振结构实际发生振动低于其振动限值时，补偿油路停止工作，施加半主动控制力。
