Abstract
The vibrator of the actuator consists of the two or more blocks of high tensile magnet, the two outboard magnet plates are the one of more middle magnet plates assembled, according to the desired sequence in series. The thickness of the magnet plates in middle of the vibrator is thicker than the outboard magnet plates. Two magnets with their homopolars face to face clamp the magnet plates in middle. The coil holder, the magnet coil and the magnet outer tube are cemented as one body. The through bolt and the sheet spring connect the vibrator and the magnet outer tube. The shortened magnetic circuit, the reduced magnetic resistance and more magnet plates utilized make the effective turns of the magnet coil increase greatly so as to increase the exciting force of the actuator greatly.
Description
Affiliated technical field
The present invention relates to mechanical field, refer in particular to a kind of concatenation type high energy electromagnetic actuator.
Background technology
Have the high energy electromagnetic actuator that in the active damping system, adopts at present, as U.S. CSA Engineering, Inc. Kai Fa a kind of electromagnetic actuator mainly is made up of one group of high strength magnet, two magnetic conductive boards, two solenoids, a magnetic conduction urceolus and two groups of springs.The magnet two ends are adsorbed with magnetic conductive board, form oscillator.Two solenoids are around to adhering to magnetic conduction urceolus two ends inwall on the contrary respectively, and the position is relative with magnetic conductive board.Springs is connected oscillator and magnetic conduction urceolus with the punching bolt from two ends, constitute an electromagnetic exciting system, its magnetic line of force flows to: the magnet N utmost point → magnetic conductive board → air gap → solenoid → magnetic conduction urceolus → another solenoid → air gap → another magnetic conductive board → magnet S utmost point → magnet N utmost point constitutes a closed magnetic path.When solenoid passed through electric current, because of two coil winding-directions are opposite, current direction was opposite, produced equidirectional active force under the effect in the opposite magnetic field of direction, and the reaction force of this power promotes oscillator.Owing to have only two magnetic conductive boards, therefore the solenoid effective turn that can arrange is less, and the electro-magnetic exciting force of generation is also less.When the big exciting force of needs, magnet consumption, current strength, volume and the cost of vibration generator are all bigger, have increased the difficulty of structural configuration and control system.
The patent No. is the disclosed high energy activator of CN 1025481C in addition, though adopted two vibration generators up and down of complete symmetry to connect and compose the composite type vibration generator, weight and volume reduces to some extent, and exciting force increases.In fact, two blocks of magnet of this type vibration generator have been formed a big magnet by housing, only constitute a closed magnetic path with two magnetic pole cover plates and housing, two moving-coils be arranged in two magnetic pole cover plates near, its structural principle still with above-mentioned CSA Engineering, the electromagnetic actuator of Inc. is basic identical.
Summary of the invention
In order to overcome the defective that existing active damping system is big with little, the high strong magnet consumption of high energy electromagnetic actuator exciting force, material cost is high, the invention provides a kind of concatenation type high energy electromagnetic actuator.It with two or more little electromagnetic exciting system string together, make full use of each independently closed magnetic path arrange solenoid, shortened magnetic circuit greatly, reduced cost, improved exciting force, be desirable exciting source and ACTIVE CONTROL actuator.
The technical solution adopted for the present invention to solve the technical problems is: the oscillator of electromagnetic actuator is made of high strong magnet and magnetic conductive board, coil retainer, solenoid and magnetic conduction urceolus cementation are integral, oscillator and magnetic conduction urceolus two ends punching bolt, pad is connected with springs, it is characterized in that: the order that the oscillator of electromagnetic actuator is pressed " outside magnetic conductive board---high strong magnet---middle magnetic conductive board---high strong magnet---...---high strong magnet---outside magnetic conductive board " by two or more than two high strong magnet and two outsides magnetic conductive board and middle the magnetic conductive boards more than one or is in series, the thickness of middle magnetic conductive board is bigger than the thickness of outside magnetic conductive board, and any two adjacent magnet homopolarities are relatively clamped middle magnetic conductive board therebetween.Solenoid equates that with the quantity of magnetic conductive board the position is relative, coil around to or wiring design make that the current direction of any two adjacent windings is opposite.The magnetic line of force of every block of magnet flows to: the magnet N utmost point → magnetic conductive board → air gap → solenoid → part magnetic conduction urceolus → adjacent solenoid → air gap → adjacent magnetic conductive board → magnet S utmost point → magnet N utmost point constitutes short closed magnetic path.There are several magnet that several groups of such closed magnetic paths are just arranged in the oscillator.When passing through electric current in the solenoid, because the current opposite in direction in adjacent two solenoids produces equidirectional active force under the effect in different directions magnetic field, the reaction force of this power promotes oscillator.The advantage of this electromagnetic exciting system is to have shortened magnetic circuit, has reduced magnetic resistance, has increased magnetic conductive board quantity, the effective turn of the solenoid that can arrange increases greatly, exciting force is able to significantly increase, and magnet consumption, current strength, material cost and vibration generator volume can reduce.
