Abstract
The invention discloses a current control device and method thereof in a suspension control system of a magneto-rheological damper. A magneto-rheological damper is suspended on a support, an acceleration sensor mounted on the support acquires vibration acceleration signals and charges of the acceleration sensor can be transmitted to a charge amplifier, and the charge amplifier converts charges into corresponding voltage values and transmits to a single-chip microcomputer in an external interruption manner. With an aim to overcome the defects that controllable current source in the suspension control system of the magneto-rheological damper is low in output current and results in poor suppression and vibration effect of the magneto-rheological damper, intelligence is greatly improved during control of the magneto-rheological damper, and train safety is effectively improved.
Description
Technical field
The present invention relates to the current control device on a kind of train and method thereof, particularly relate to one and be applied to current control device and method thereof in MR damper hanging control system.
Background technique
International train industry attaches great importance to the vibration control of train, object reduces vibration to driver fatigue and raising traffic safety, because MR damper suppresses the vibrating effect of train good, so this device generally all installed by existing train, each vehicle manufacturers is in order to improve the competitive ability of train, vibrate less in running except making train, also constantly improve the vibration damping intelligent of train, current magnetorheological damping hanging control system is when controlling MR damper, too small owing to controlling electric current, MR damper is made to suppress the effect in vibration bad, and existing magnetorheological damping hanging control system realizes controlling by pure hardware circuit, so not only cost of production can be increased, and the effect in intelligent control is not fine.
Summary of the invention
One is the object of the present invention is to provide to be applied to current control device and method thereof in MR damper hanging control system, solve current magnetorheological damping hanging control system when controlling MR damper, too small owing to controlling electric current, MR damper is made to suppress the effect in vibration bad, and existing magnetorheological damping hanging control system realizes controlling by pure hardware circuit, so not only cost of production can be increased, and the effect in intelligent control not good problem.
The present invention realizes like this, one is applied to current control device in MR damper hanging control system, it comprises acceleration transducer, charge amplifier, single-chip microcomputer, field-effect transistor, MR damper, it is characterized in that: described acceleration transducer, charge amplifier, single-chip microcomputer, field-effect transistor are connected successively with MR damper.
A/D conversion is carried out between described charge amplifier and single-chip microcomputer.
D/A conversion is carried out between described single-chip microcomputer and charge amplifier.
Described single-chip microcomputer is the single-chip microcomputer of STC12C5A60S2.
One is applied to current control method in MR damper hanging control system, its technical step is: 1, MR damper is suspended on support, gather vibration acceleration signal by rack-mount acceleration transducer, acceleration transducer passes to charge amplifier in the form of a charge afterwards; 2, the quantity of electric charge is converted into corresponding magnitude of voltage by charge amplifier, passes to single-chip microcomputer in the mode of external interrupt, and single-chip microcomputer, by the process of external interrupt program, exports rectangular pulse signal; 3, the signal that single-chip microcomputer output duty cycle is adjustable carrys out the guide channel width between controlling filed effect transistor drain-source pole, thus the electric current between drain-source pole must control, thus controls the characteristic of MR damper, and the vibration of suspension system is suppressed.
Technique effect of the present invention is: the present invention is in order to overcome train in the process of moving, because in MR damper hanging control system, controllable current source output current is too small, thus cause the problem that MR damper suppresses vibrating effect not good, the intelligent ability of MR damper control procedure is improved greatly, thus effectively raises the Security of train.
