Tuning quality damper with adjustable nonlinear energy trap and adjustable inerter
The invention discloses a tuning quality damper with an adjustable nonlinear energy trap and an adjustable inerter. The tuning quality damper comprises a shielding box, a nonlinear energy trap moduleand an inerter damping module. The nonlinear energy trap module is arranged in the shielding box, the inerter damping module is arranged above the shielding box, and a base of the shielding box is fixed to a main structure. The nonlinear energy trap module comprises multiple groups of permanent magnets, restoring force adjusting table seats, a sliding mass block and a sliding rail. The restoring force adjusting table seats are arranged on the two sides of the sliding mass block in pairs, and each group of permanent magnets are separately arranged on the restoring force adjusting table seats and the sliding mass block. The inerter damping module comprises a stiction damper, a transmission mechanism and flywheels. The stiction damper is fixed to the sliding mass block, the flywheels are rotationally arranged above the shielding box, and the transmission mechanism is connected between the stiction damper and the flywheels. Vibration energy of the main structure is absorbed through the nonlinear energy trap module, the vibration energy is dissipated and efficiency-improved through the inerter damping module, and the damping control effect is good.
