Abstract:
A new semi-active MR-TMD (magnetorheological tuned mass dampers) actuator system for structural vibration control was proposed, which needn’t the complicated, huge and costly hydraulic actuator system. The feasibility and effectiveness of MR-TMD for structural vibration control under harmonic excitations were simulated and analyzed by using the semi-active control algorithms proposed by the authors. Magnitude-frequency property of TMD,semi-active MR-TMD and AMD were compared by using the same model structure. The maximum and minimum damping force and the adjustable ranges influencing on MR controlled system were analyzed. The optimum parameters are given for MR-TMD control system. Numerical simulations show that MR-TMD system can effectively reduce the reaction by the structure, MR-TMD control system is prior to the optimum TMD control system with the same mass block parameters, and prior to the optimum TMD system with the same mass parameters as a semi-active mass actuator, and it so has wider frequency. The structural reaction of the controlled system is reduced by 15%; the standard variation is reduced by 58% compared with the TMD con trolled system; the static magnitude controlled structure is greatly reduced by MR-TMD. The authors propose that it is essential for MR-TMD vibration control system to choice the reasonable parameters such as the maximum damping force, the minimum damping force and the adjustable multiple of MR damper. The performance with the reasonable damping parameters of MR damper excelled TMD and the control effect is close to AMD.
