Self-adaptive variable-rigidity tuned mass damper
The invention relates to a self-adaptive variable-rigidity tuned mass damper, and relates to the technical field of engineering structure vibration reduction. The self-adaptive variable-rigidity tuned mass damper comprises a shell, a mass block, a damping mechanism, an adjusting device and a locking mechanism, wherein the shell is used for being connected with an engineering structure, and a containing space is formed in the shell; the mass block is located in the containing space, and a spring is connected to the mass block; the damping mechanism is arranged in the containing space; one end of the adjusting device is arranged on the shell, and the other end of the adjusting device is movably connected with the spring; the locking mechanism is connected with the adjusting device and is clamped on the spring; and the adjusting device is used for rotating to drive the locking mechanism to move on the spring in the direction close to or away from the mass block so as to change the position of the locking mechanism clamped on the spring and change the effective number of turns of the spring. Therefore, the purpose of changing the vibration frequency of the tuned mass damper is achieved.
本申请涉及一种自适应变刚度调谐质量阻尼器，涉及工程结构减振技术领域，其包括壳体、质量块、阻尼机构、调节装置和锁止机构，壳体用于与工程结构连接，且其内具有收容空间；质量块位于收容空间内，且其上连接有弹簧；阻尼机构组设于收容空间内；调节装置一端组设于壳体上，另一端与弹簧活动连接；锁止机构与调节装置连接，并卡持于弹簧上；以及，调节装置用于旋转，带动锁止机构在弹簧上沿靠近或远离质量块的方向移动，以改变锁止机构卡持在弹簧上的位置，并改变弹簧的有效圈数。从而达到改变调谐质量阻尼器的振动频率的目的。
