Embodiment 1

[0019] As a preferred embodiment of the present invention: the primary damping module 2 includes a No. 1 sleeve 201, and a No. 1 inner spring 202 is arranged inside the No. 1 sleeve 201, and the inside of the No. 1 sleeve 201 is close to the top of the No. 1 inner spring 202 Connected with a No. 1 telescopic column 203, the outer surface of the No. 1 telescopic column 203 is provided with a No. 1 outer spring 204, and the top of the No. 1 outer spring 204 is connected with a buffer plate 205. After the No. 1 sleeve 201 receives the vibration force, the vibration force is transmitted to No. 1 The inner spring 202 and the No. 1 inner spring 202 are extended or shortened. When the No. 1 inner spring 202 is extended or shortened, the No. 1 telescopic column 203 moves up or down on the inner wall of the No. 1 sleeve 201, and the No. 1 inner spring 202 Squeeze, at this time the No. 1 outer spring 204 is extended or shortened under the force of the No. 1 sleeve 201, and the No. 1 oute...

Embodiment 2

[0021] As a preferred embodiment of the present invention: the secondary damping module 3 includes a No. 2 sleeve 304, and a No. 2 inner spring 301 is installed inside the No. 2 sleeve 304, and the inside of the No. 2 sleeve 304 is close to the No. 2 inner spring 301 No. 2 telescopic column 302 is connected to the top of the No. 2 telescopic column 302, and No. 2 outer spring 303 is arranged on the outer surface of No. 2 telescopic column 302. The buffer plate 205 transmits the shock force after the primary vibration reduction to No. 2 sleeve 304, and No. 2 sleeve 304 receives Move up after force, now No. 2 inner spring 301 and No. 2 outer spring 303 are compressed, and the reaction force produced after No. 2 inner spring 301 and No. 2 outer spring 303 are compressed can carry out secondary vibration reduction to vibration force.

Embodiment 3

[0023] As a preferred embodiment of the present invention: the adjustment module 4 includes an electro-hydraulic push rod 401, and an extension spring 402 is installed on the inside of the electro-hydraulic push rod 401. When the electro-hydraulic push rod 401 is in operation, the electro-hydraulic push rod 401 drives the extension spring 402 prolongs or stretches, and electrohydraulic push rod 401 drives No. 2 inner spring 301, No. 2 outer spring 303 and No. 1 inner spring 202, and No. 1 outer spring 204 prolongs or shortens simultaneously, changes No. 2 inner spring 301, No. 2 outer spring 303 and The anti-vibration capabilities of the No. 1 inner spring 202 and the No. 1 outer spring 204 can achieve the purpose of adjusting the amplitude.

Abstract

The invention discloses a shock mitigation system capable of adjusting the amplitude. The shock mitigation system comprises a moving module, the top end of the moving module is connected with a stressmodule, the top end of the stress module is connected with a primary damping module, and the top end of the primary damping module is connected to a secondary damping module. The shock mitigation system is provided with an electrohydraulic push rod and a tension spring, when the electrohydraulic push rod is operated, the electrohydraulic push rod drives the tension spring to extend or stretch out, and meanwhile, the electrohydraulic push rod changes the distance between a buffer plate and the stress module to drive a second inner spring and a second outer spring to be prolonged or shortened;and meanwhile, the electrohydraulic push rod can change the distance from the top end of a second telescopic column to the bottom end of a second sleeve when being operated, so that a first inner spring and a first outer spring are driven to be prolonged or shortened, the anti-vibration ability of the second inner spring, the second outer spring, the first inner spring and the first outer spring is changed, and the purpose of adjusting the amplitude is achieved.

Description

technical field [0001] The invention relates to the field of vibration reduction, in particular to a vibration reduction system with adjustable amplitude. Background technique [0002] Vibration reduction is to eliminate the vibration source, that is, to eliminate or reduce the exciting force. If the rotating machine is dynamically balanced, a dynamic vibration absorber (composed of a weight with a mass of m and a spring with a stiffness of k) is installed on the machine with an exciting force. [0003] However, the current damping system cannot adjust the vibration amplitude according to real-time needs, resulting in a low applicability of the damping system. Contents of the invention [0004] The object of the present invention is to provide a vibration damping system with adjustable amplitude, so as to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object, the present invention provides the following tech...
