Product introduction:
Tuned mass damper (TMD) is a kind of structural vibration reduction control equipment, through the auxiliary mass block with specific mass and stiffness connected to the main structure, using its own vibration characteristics to reduce the dynamic response of the main structure under earthquake, wind or environmental excitation. The TMD system is mainly composed of three parts: mass block, spring and damper. The working principle is to adjust the frequency of the TMD, so that it is close to or equal to the vibration frequency of the main structure, so as to achieve the vibration reduction effect.
Core advantage:
1.After the optimized design of the TMD system, the dynamic response of the main structure under the action of earthquake and wind is reduced by 30%~60%, and the vibration reduction effect is significant.
2.The frequency of the TMD system is adjustable within ± 20%, which can adapt to different working conditions and improve the vibration reduction effect.
3.The system is compact and reasonable structure with high space utilization rate, high flexibility and convenience in practical application.
4.The system has wide applicability, not only for high-rise buildings, bridge and other structures, but also for machinery, aerospace and other fields.
Application case:The product is installed and used in the Linjiang Creek Bridge in Yichang.
