Abstract

The invention discloses a box type liquid damper comprising a box body, an upper damping plate and a lower damping plate. The box body is provided with a top plate, side plates and a base plate. The upper damping plate and the lower damping plate are provided with multiple through holes. The upper damping plate is connected to the lower surface of the top plate through springs. The lower damping plate is connected to the upper surface of the base plate through springs. The inner portion of the box body is divided by the upper damping plate and the lower damping plate into an upper liquid chamber, a middle liquid chamber and a lower liquid chamber. The box body is filled with damping liquid. The liquid level of the damping liquid is higher than a top dead center of the travel of the upper damping plate. Compared with a liquid damper in the prior art, the box type liquid damper expands the work frequency range of the liquid damper and can dynamically change the damping of the structure,and the liquid damper can efficiently consume energy and attenuate vibration.

Description

technical field [0001] The invention relates to the field of damping and vibration reduction, in particular to a box type liquid shock absorber. Background technique [0002] In recent years, with the rapid development of urbanization, the scale of large cities and urban agglomerations is constantly expanding, and the impact of traffic systems such as automobiles, subways, and intercity railways on adjacent building structures is becoming more and more severe, which seriously affects people. work and daily life. To attenuate the effects of vibrations on people living and working in buildings, liquid dampers have been extensively studied. However, the existing liquid shock absorber has a narrow frequency range of vibration reduction, cannot perform dynamic damping adjustment, and is sensitive to changes in the working environment, which seriously affects its vibration reduction effect. [0003] Therefore, how to increase the operating frequency range of the liquid damper so...
