Problems solved by technology

For example, the magnetorheological elastomer frequency-shifting vibration absorber disclosed in the patent application number 200520076452.4 has a good effect on the vibration control of flexible structures, but it is difficult to implement large-scale vibration control
In addition, the patent application number 201310014657.9 discloses a flexible manipulator vibration damping device and method based on magneto-rheological technology, which can change the stiffness parameters of the shock absorber by adjusting the voltage of the electromagnetic coil. The vibrator of the system has high requirements on the strength of the magnetorheological elastomer, which limits the application of its vibration absorber

Abstract

The invention relates to a vibration damping device applied in the fields of flexible mechanical arm, engine system vibration damping and the like, in particular to a vibration damping device based on magneto-rheological technology. A shock absorber based on magneto-rheological technology, including: a fixed seat, a shock-absorbing module and a control module. The fixed base is the vibration control object; the vibration damping module is composed of magnetic circuit iron core, magnetorheological elastomer, vibration-absorbing mass block, coil baffle, excitation coil, upper splint, magnetic isolation block, and lower splint; the control module is composed of acceleration sensor, Composed of data acquisition system, control host and DC power supply. By adjusting the excitation current on the excitation coil, the rigidity of the magneto-rheological elastic body is adjusted, so as to meet the vibration frequency requirement of realizing the vibration reduction of the vibration control object. The invention has the advantages of good damping effect, wide applicable frequency range, less energy consumption, simple structure and the like.

Description

technical field [0001] The invention relates to a vibration damping device applied in the fields of flexible mechanical arm, engine system vibration damping and the like, in particular to a vibration damping device based on magneto-rheological technology. Background technique [0002] Shock absorbers play an important role in flexible robotic arms and engine systems. When the flexible mechanical arm and the engine system are working, their vibration will affect the reliability and life of the equipment, and will cause noise and vibration in the working environment of the equipment. Therefore, aiming at the vibration problems of the flexible manipulator and the engine system, it is of great significance to design a vibration control device for the flexible manipulator and the engine system. [0003] In order to reduce the influence of the vibration of the flexible manipulator and the engine system, a shock absorber is usually attached to the vibration control object, and the...
