电流变液在大射电望远镜馈源支撑系统风振半主动控制中的应用
Application of electrorheological fluids in semi-active wind vibration control of the feed supporting system for the large radio telescope
摘要
Abstract
Based on the introduction to the electrorheological (ER) fluidand the various models of dampers using ER fluid, and considering the wind induced vibration of the feed supporting system with cables for the large spherical radio telescope, a novel ER damper is designed to realize the semi-active control of this vibration. The model of the designed ER adaptive damper is described in detail, and the strategy of the semi-active control is proposed. The numerical simulation results have shown the validity of the designed adaptive ER damper to suppress the wind vibration of the feed supporting system, which has completely solved the additional damping control for the suspended drive system.关键词
