Title: Changfei Ma: Innovator in Bridge Vibration Control

Introduction

Changfei Ma is a notable inventor hailing from Hubei, China. He has made significant contributions to the field of bridge vibration control, showcasing his innovative spirit through his patented invention. His work focuses on enhancing the structural integrity and longevity of bridges by mitigating vibrations effectively.

Latest Patents

Changfei Ma holds a patent for an "Ultra-low frequency tuned liquid mass damper and design method of the same." This invention relates to an ultra-low frequency (ULF) tuned liquid mass damper that is designed specifically for bridge vibration control. The tuner damper consists of a damping box that houses a spring set attached to a mass block, with the damping box filled with damping liquid. This innovative design allows the mass block to be either completely or partially immersed in the liquid, achieving a damping ratio between 3% and 35% and an inherent frequency range of 0.05 to 0.5 Hz. The ULF tuned liquid mass damper leverages the buoyancy effect of the liquid, effectively using its additional mass to reduce structural vibrations while simultaneously minimizing spring static elongation and installation space requirements.
