In order to solve the shortcomings of traditional TLDs (tuned liquid dampers), such as their narrow frequency bands and their occupation of large amounts of space, based on deep-water theory, a new type of TLD incorporating Karmen vortex street theory is proposed and named as KV-TLD. A shaking table experimental test is conducted to fully analyze its vibration damping characteristics and its effectiveness in terms of vibration control is confirmed. Through comparison with a traditional TLD, the superiority of KV-TLD is verified. By analyzing parameters such as the mass ratio and the frequency ratio, it is found that a larger mass ratio means a better damping effect. When the frequency ratio is close to 1.0, the damping effect is better, while the vibration damping advantage of KV-TLD is much lower. Good performance in terms of installation, a wide frequency band, and damping effect means that KV-TLD is superior in terms of actual engineering application possibilities, and can also act as a good reference for subsequent engineering projects.
