Abstract

The invention relates to the field of applying magnetorheological damping technology, and provides a magnetorheological damping control method: using giant magnetostrictive materials, permanent magnets and yokes at both ends to form an input magnetic circuit, using permanent magnets, yokes, magnetic The rheological medium and the soft magnet form an output magnetic circuit. The method provided by the present invention saves the coil and the external power supply, and can realize the conversion of the vibration mechanical energy of the controlled structure to the magnetic field energy with only a small amount of materials. Fast, wide frequency band and better cushioning of impact loads.

Description

technical field

[0001] The invention relates to the field of applying magneto-rheological damping technology. Background technique

[0002] Magnetorheological damping technology is to use the magnetorheological effect (Magnetorheological Effect) to achieve damping. The magnetorheological damping device made by utilizing the magnetorheological effect has the functions of rapid response, easy control, low energy consumption and large damping force. It has been widely used in vehicle suspension systems, building structures (such as bridges, dams, high-rise buildings, etc.), brakes and clutches, recoil control of naval guns in military equipment, and vibration reduction of helicopter rotors. Active and semi-active control of vibrating structural systems.

[0003] Currently available magneto-rheological effect technology requires an external magnetic field to function. Electromagnet principles (such as solenoid coils) are used to obtain the required controllable magnetic field,...
