A high damping fluid damper

Abstract

The invention provides a high-damping fluid damper, which belongs to the technical field of vibration reduction. The damper includes high-damping structural parts, viscous fluid and upper and lower high-rigidity panels. The high-damping structural parts are integrally processed to complete a structure with a gap in the middle. It is composed of a damping disc and a buffer chamber. The buffer chamber is connected to the damping disc. It is composed of multiple damping disc structural parts inside and outside, and the damping disc structural parts are connected by holes, the viscous fluid enters the inner cavity of the structure through the oil inlet, and the upper and lower high rigidity panels are respectively pasted on the upper and lower end faces of the high damping structural parts. When the upper end face of the high-damping fluid damper is subjected to a compressive load, the upper end face moves downward, and the structure undergoes lateral deformation, resulting in a change in the volume of the void in the middle of the structure, and the viscous fluid in the inner cavity of the structure is forced to flow to the outer cavities on both sides, outputting damping force , to convert mechanical energy into internal energy, so as to realize dynamic vibration reduction and isolation with wide frequency and high damping. The invention has simple structure and high damping efficiency, can effectively reduce costs, and has strong practicability.
