TMDTuning mass dampersWhat are the features of TMD dampers that can lower objects with much less weight than the object (structure).Maximum amplitude, thus preventing discomfort, breakage or complete damage. They are often used in buildings, power transmission, cars, ships, and other aspects of life. One is a viscous TMD damper, that is, a TMD damper that uses a viscous method for energy consumption, and the other is an eddy current TMD damper, that is, it is adoptedEddy currentTMD damper for energy consumption. Tuning mass damper is also calledPower Shock Absorber, is a kind of structural passive control measure, mainly used in wind resistance and improving human comfort.
First of all, "willTuning mass dampers(TMD) is set at the bottom, the center of gravity is lower and more stable" focuses on reducing the gravity second-order bending moment effect of TMD, from this point of view, setting the TMD at the top will indeed produce a greater gravity second-order bending moment effect, which is also one of the reasons why TMD should consider the safety issues caused by increased mass when designing.
In SAP200 softwareTuning mass damper (Tuned Mass Damper, TMD for short) to the top of the three-layer frame, you can follow these steps:
Welcome to read, this is a narrative article about TMD shock absorption tuning mass dampers, edited by Hebei Luze Technology - focusing on steel structure bearings,Viscous damperDesign and production.
The Tuned Mass Damper (TMD) consists of a block, a spring and an energy-dissipating damping system. The vibration frequency is adjusted to the vicinity of the main structure frequency and the structural resonance characteristics are changed to achieve the purpose of vibration reduction.
