Description
Technical Field
The utility model relates to a but spacing frequency modulation mass damper system.
Background
When the frequency of human motion load or wind load is close to the natural frequency of the broken flexible structure, the structure resonates, which causes discomfort to people and can damage the structure itself in serious cases. The frequency modulation mass damper (TMD) system is one of the structural passive damping control systems, and is composed of a main structure and a substructure which is attached on the main structure. The main structure is excited to vibrate, the sub-structure produces an inertial force acting in the direction opposite to the vibration direction of the structure to damp and control the vibration reaction of the main structure. The substructure acts as a damper during damping control, so the substructure is referred to as a "tuned mass damper".
The existing frequency modulation mass damper only considers adjustable rigidity and mass, has no additional limiting device and no frequency modulation function, and cannot achieve the best shock absorption effect if the frequency modulation mass damper generates lateral displacement.
