Damping device

Abstract

The invention provides a gap-adjustable and rigidity-variable elastic micropowder particle collision damping device. By using the damping device, the aims that the collision process is visible, the collision gap ratio is adjustable and the collision rigidity is variable are achieved. The damping device provided by the invention comprises a base and a collision damper, wherein the base is used for supporting the collision damper, and the collision damper is used for absorbing vibration energy. The base comprises a base body and a sliding rail, wherein the base body is used for supporting the collision damper through the sliding rail and a spring device; and the sliding rail is detachably fixed on the base body and is used for slidably supporting the collision damper. The collision damper comprises a damper shell, at least one spring device, at least one piston body, a ball body and powder particles, wherein the damper shell is provided with a shell body with a round cross section and sealing ends at two ends; the ball body is arranged in the damper shell and is used for absorbing the vibration energy generated by collision among the sealing ends, the piston body and the powder particles; and the powder particles are arranged in a cavity together with the ball body and are used for absorbing the vibration energy when coming into collision with the ball body.

Description

technical field [0001] The invention relates to a damping device, in particular to an elastic impact damper with adjustable gap and variable stiffness micropowder. Background technique [0002] Collision damping is a kind of passive control, and its working principle is to use the impactor (metal ball) to collide with the main system during the vibration process, so as to control the collision response. [0003] A collision damper is a device that reduces the range of motion, consumes motion energy, and achieves a vibration reduction effect through resistance; a vibration damper has an obvious feature that it can achieve vibration reduction through its own particularity without external energy input. Vibration effect, so that it can work normally under extremely harsh conditions and achieve obvious results. The traditional collision damper is to add a spherical impactor (sphere) into the closed cavity. The spherical impactor can continuously impact the two ends of the conta...

Problems solved by technology

[0004] However, until now, the invariable gap ratio, fixed stiffness (constituting a damper-fixed spring device) and the invisibility of the motion law of the impactor (metal ball) have made the damper a damper-use function, hindering It hinders the flexible use of the damper, hinders the observation of the damper impactor (metal ball), and increases the cost of the damper during use
