【Abstract】 A new semi-active MR-TMD control device was proposed,which is installed on the TMD with a magneto-rheological damper.The feasibility and effectiveness of semi-active MR-TMD control system for structural vibration control under rectangular periodic excitations were simulated and analyzed by adopting one semi-active control algorithm proposed in the article.The control effect of semi-active MR-TMD,passive TMD and active AMD were compared by adopting the same model structure.Simulations numerical show that the damping performance of using semi-active MR-TMD control is better than that of using passive TMD control and active AMD control.更多还原
