A Passive Adaptive Suspended Mass Pendulum to Compensate Detuning Due to Large Swing Angle

Abstract: The suspended mass pendulum (SMP) conventionally used is a type of frequency sensitive vibration control device. It is vulnerable to detuning due to large amplitude oscillations, which can lead to a significant loss in vibration control performance. Although active or semi-active control systems can solve the problem of frequency detuning, the reliability and stability of the sensors and actuators in the control system are difficult to guarantee for large-scale civil structures. To overcome this issue, this st… Show more

“…Thus, the period of the pendulum moving along a cycloidal trajectory is constant, which is independent of the swing angle. As illustrated in Figure 2, suppose that the motion trajectory (ABtrue⌢) of the IPTMD is a cycloid; then, the parametric expressions of ABtrue⌢ for the IPTMD are as follows (Huo et al, 2021). where φ is the angle formed by x -axis and the tangent of ABtrue⌢; a is a constant coefficient, which is determined by the initial pendulum length.

“…FATMD can be adjusted to the natural frequency of TMD by changing its stiffness or mass [ 18 , 19 , 20 , 21 , 22 ]. Chifley Tower [ 23 ], Taipei 101 [ 24 ] and Shanghai Tower [ 25 ] were adjusted to the natural frequency of TMD by artificially changing the pendulum length of the pendulum TMD, but this artificial adjustment method is to make the TMD meet the expected design requirements in the installation process, and cannot complete the real-time adjustment of the TMD in the working process. To realize the real-time adjustment of the natural frequency of TMD, Sun et al [ 26 ] identified the natural frequency of the main structure by short-time Fourier transform (SFT) [ 27 ], so that the natural frequency of FATMD matches the natural frequency of the main structure.…”
