The system comprises a vibration arm, a vibration reducing device and a control device; the vibration reducing device comprises a left pressing plate, a right pressing plate, a magnetic separation plate, a pressing plate fastening piece, a double-port iron core, a magnet exciting coil, a coil baffle plate, an upper clamping plate, a lower clamping plate, a clamping plate fastening piece, a triangular bracket, a bracket fastening piece, a support bearing, an oscillation shaft, a vibrator, a magnetorheological elastomer and a pendulum bob. The system can generate a higher magnet exciting magnetic field to improve resistance to extreme vibration conditions, observes the vibration change conditions more directly through the oscillation amplitude of the pendulum bob, reduces the falling risk of the vibrator from the elastomer, and importantly, achieves prominent vibration reducing effect on elastic vibration in actual application.

Description

technical field [0001] The invention relates to applications in the field of mechanical vibration, in particular to a swing vibration damping system based on magnetorheological technology, which can be specifically applied to the fields of flexible mechanical arm vibration damping, engine vibration damping and the like. Background technique [0002] In recent years, with the development of manipulator technology, the application of lightweight, fast, and high-load-to-weight ratio flexible manipulators has become a trend in industrial manufacturing and aerospace. However, the long-term continuous vibration of flexible manipulators directly affects The grasping efficiency, accuracy and service life of the manipulator are not limited, and the dynamic instability under the action of modal nonlinear coupling may directly lead to the paralysis of the flexible manipulator system; The good engine performance determines the mobility, comfort and stability of the entire equipment.

Problems solved by technology

At the same time, most of the current systems using magnetorheological elastomers have significant problems of weak excitation magnetic field, poor observability and system instability, which lead to failure to be successfully used in experiments or practical applications.

At present, there is a lack of a vibration damping system that successfully utilizes the theory of nonlinear vibration internal resonance and the characteristics of magnetorheological elastomers, and has strong excitation ability and stable performance.
