Problems solved by technology

The limitation of another commonly used viscous damper is that the viscous oil cylinder needs to achieve the viscosity coefficient required by the design. Usually, the pressure of the liquid in the oil cylinder is very high, so it is very difficult to ensure the sealing performance of the damper throughout the service life. , if the viscous liquid leaks, it will seriously affect the function of the damper; and the viscous liquid involved in dissipating energy only takes effect when it passes through the small hole instantaneously, thus limiting the improvement of energy consumption efficiency per unit time

Abstract

The invention discloses a solid particle damper device, and relates to the technical field of dampers. The solid particle damper device comprises a damper cylinder and a damping rod. The damper cylinder comprises a first cavity and a second cavity. A piston is arranged between the first cavity and the second cavity. A spring device is arranged in the first cavity. One end of the spring device is fixed to the inner wall of the damper cylinder. The other end of the spring device is fixed to the piston. A plurality of solid spherical particles are arranged in the second cavity. The damping rod sequentially penetrates through the spring device of the first cavity and the piston to enter the second cavity and is connected with the solid spherical particles in a friction mode. The solid particle damper device can be suitable for the application fields of shock insulation of high-rise buildings, shock absorption of large bridges, collision buffering of high-speed vehicles, braking of new-concept weapons and the like, and is a novel damper which has the advantages of being large in bearing power, low in cost, high in efficiency, free of maintenance, high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of dampers, in particular to a solid particle damper device. Background technique [0002] Damping is a variety of friction and other hindrances that attenuate free vibration, and a device that can provide resistance to movement and consume movement energy is called a damper. Dampers are widely used in aerospace, military, guns, automobiles and other industries to reduce vibration and energy. Damping can be divided into particle damping, viscous damping, joint surface damping and Coulomb friction damping, impact damping, electromagnetic effect damping, etc. [0003] At present, the research on particle dampers at home and abroad is focused on using particles as the filler of the vibrating body, and the application field is limited to various beam structures to suppress their vibration at different frequencies. The limitation of another commonly used viscous damper is that the viscous oil cylinder must achi...
