Active tuning mass damper and active tuning method
The invention relates to the technical field of damping vibration attenuation, in particular to an active tuned mass damper and an active tuning method, and the active tuned mass damper comprises a tuned mass damper, a first vibration sensor, a second vibration sensor, an actuator and a controller. The tuned mass damper comprises a mass block, a spring and a damping piece, one end of the spring is connected with the mass block, and the other end of the spring is connected with a structure to be damped; the damping piece is arranged between the mass block and the structure to be damped; the first vibration sensor is arranged on the mass block, and the second vibration sensor is arranged on the structure to be damped; one end of the actuator is connected with the mass block, and the other end is connected with the damped structure; the controller controls the magnitude of external force applied to the mass block by the actuator according to vibration signals detected by the first vibration sensor and the second vibration sensor. The problem that the scheme in the prior art cannot actively perform control frequency adjustment according to the frequency of a controlled structure and is poor in adaptability can be solved.
本发明涉及阻尼减振技术领域，具体涉及一种主动调谐质量阻尼器及主动调谐方法，该主动调谐质量阻尼器，包括：调谐质量阻尼器、第一振动传感器、第二振动传感器、作动器和控制器。调谐质量阻尼器包括：质量块、弹簧和阻尼件，其中，弹簧，其一端与质量块连接，另一端与被减振结构连接；阻尼件设在质量块和被减振结构之间；第一振动传感器在质量块上，第二振动传感器设置被减振结构上；作动器一端与质量块连接，另一端与被减振结构连接；控制器根据第一振动传感器、第二振动传感器检测的振动信号，控制作动器向质量块施加外力的大小。能够解决现有技术中的方案不能根据受控结构的频率主动进行控制频率调整，适应性差的问题。
