Abstract

When the natural frequency of pendulum-type tuned mass damper（PTMD） is consistent with that of the main structure

the vibration can be controlled effectively. Because the engineering structural design frequency may be different from the actual frequency

together with the accumulated damage during operation

the actual natural frequency of the main structure will deviate from that of the PTMD

hence greatly reducing the effect of PTMD on controlling vibration. In order to overcome the deficiency of traditional PTMDs

an adaptive PTMD device is proposed in this paper on the basis that the frequency of PTMD is only related to the pendulum length. Short-time fourier transform and natural excitation method are used to identify the natural frequency of the main structure

and then

the step motor initiates spontaneously to change the pendulum length to adjust its frequency to match the main structural frequency. This paper proposes a test apparatus of adaptive PTMD

and simulates its structural responses under different excitations. The results show that the adaptive PTMD can precisely identify the structural frequency

and it can improve the structural equivalent damping ratio and reduce the structural acceleration response. Adaptive PTMD can improve the vibration control effect of PTMD

improve the safety and durability of a structure

and extend its service life. Moreover

it is simple and energy efficient. Therefore

adaptive PTMDs have a bright prospect in engineering applications.
