Title: Innovations of Xiaopeng Chai in Bridge Vibration Control
Introduction
Xiaopeng Chai is a notable inventor based in Hubei, China. He has made significant contributions to the field of bridge vibration control through his innovative designs and patents. His work focuses on enhancing the stability and safety of structures subjected to vibrations.
Latest Patents
One of Xiaopeng Chai's key inventions is the ultra-low frequency tuned liquid mass damper. This invention relates to the technical field of bridge vibration control. The tuned damper includes a damping box equipped with a spring set, which is secured at one end to the damping box, while the other end is connected to a mass block. The damping box is filled with damping liquid, allowing the mass block to be completely or partially immersed in the liquid. The damping ratio of this damper ranges from 3% to 35%, with an inherent frequency between 0.05 to 0.5 Hz. This innovative design fully utilizes the additional mass of the damping liquid and leverages the buoyancy effect to maintain structural vibration frequencies below 0.5 Hz. It also significantly reduces spring static elongation, damper spring consumption, and installation space, addressing practical construction limitations.
