Shown in each accompanying drawing, electric reverse vibration generator of the present invention is mainly by relatively rotating module I and the stuck-module II is formed.
Connect by a pair of spring 14 between them, can make relative resilient and rotate.Spring 14 in this enforcement is a garter spring, and this is typical embodiment and non-limiting.
As an example, the module I that relatively rotates wherein comprises heart circle 0, inner ring 1, and centre circle 2, outer ring 3, and the magnetic patch 4,5,6,7 of annular, this magnetic patch is preferably the neodymium iron boron material, and is certainly, also non-limiting.Heart circle 0, inner ring 1, centre circle 2 and outer ring 3 are fixed together by a pair of spoke beam 8 of the 180 ° of central angles of being separated by.
Wherein Huan Xing ndfeb magnet 4,5,6,7 belongs to permanent magnet, and for the magnetic field generator among the present invention is a kind of embodiment, other also comprises the magnetic field of realizing by galvanomagnetic effect, as utilizes conductive coil to produce magnetic field, or the like.
Between spoke beam 8, magnetic patch 4 and 5 usefulness bonding agents or other suitable mode are fixed on the outside of inner ring 1, and are the symmetric arrangement state.Similarly, magnetic patch 6 and 7 usefulness bonding agents or other suitable mode are fixed on the inboard of outer ring 3, also are symmetry shape between spoke beam 8, and magnetic patch 4 and 6, magnetic patch 5 and 7 be respectively across centre circle 2 positioned opposite like this, and the magnetic direction of magnetic patch along circle radially.
In the said structure, all arrange magnetic field generator in the both sides of described conductive coil 11 and 12, in addition, can also be separately in the inboard or the outside arrange magnetic field generator.
The stuck-module II comprises a pair of annular collar 9 and 10, twines and be fixed on the conductive coil 11 and 12 on the lasso, and X type fixed support 13.Lasso 9 and 10 is enclosed within respectively on the centre circle 2, symmetric arrangement between spoke beam 8, therefore the inboard of lasso does not contact fully with centre circle 2, can move freely with respect to centre circle 2, Here it is described electric reverse vibration generator relatively rotate the reason place that module I can relative fixed module II be rotated.
Tightly around also using adhesive on lasso 9, conductive coil 12 is tightly around also using adhesive on lasso 10 for conductive coil 11.Such structure makes the both sides of each group copper coil all be between described magnetic patch and the centre circle 2 in the air gap of formed annular radial magnetic field, and the trend of copper coil, also is sense of current, is vertical with magnetic direction.Described lasso need adopt nonmagnetic substances such as copper, aluminium or plastics.
In order to allow lasso 10 be enclosed within on the centre circle 2, centre circle 2 can disconnect at spoke Liang8Chu, earlier lasso 10 is enclosed within the outside of centre circle 2, then centre circle 2 is fixed by bolts on the spoke beam 8.
Except above-mentioned member, described vibrator other parts also comprise: fixed block 15, axle 16, rolling bearing 17, brush 18, spring base 19 and spring base 20.In the X type fixed support 13, be not provided with between the adjacent bifurcated of conductive coil 12, comprise position, two places altogether, the one place at least in this position, two places is provided with the fixed block 15 that relatively rotates the module I slewing area in order to qualification.
Fixed block 15 is fixed on the position of close spoke beam 8 on the centre circle 2, and its effect is the motion of restriction lasso, prevents that lasso impacts spoke beam 8 under the overload situations.
In fact axle 16 is exactly a part that needs the rotating machinery axle system of exciting, and rolling bearing 17 is supported on heart circle 0 on the axle 16, makes the above-mentioned module I that relatively rotates at heart circle 0 and place thereof to rotate with respect to axle system.
Brush 18 is fixed on the axle 16, guarantees to give under the situation of total system high speed rotating conductive coil 11 and 12 that the alternating current of variation is provided.
Said fixing module II, promptly lasso 9 and 10 comprises top coil 11 and 12, is fixed on the axle 16 by X type fixed support 13, rotates with axle system.
Aforesaid a pair of spring 14 is arranged symmetrically in the outside of outer ring, each helical spring end is fixed on the outer ring by spring base 19, the other end by spring base 20 be fixed on axle rigid attachment axle system together on, can directly be fixed on the axle by the structure of extending.
Like this, the above-mentioned module I that relatively rotates can be by rolling bearing 17, under the effect of spring 14, with respect to said fixing module II and the turning axle system that acted on, swings back and forth around its stable position.
Further set forth other structural feature of described torsional activator:
For example and without limitation, above-mentioned magnetic patch and centre circle 2 formed air-gap magnetic field directions be circular radially, in the magnetic field generator of described centre circle 2 both sides positioned opposite, the relation between the magnetic direction can have two kinds of selection schemes:
First kind is that the magnetic direction of the magnetic patch of both sides positioned opposite repels each other on the contrary, and second kind is that both phase homophases are inhaled.Introduce respectively below:
First kind of scheme at first is described.This moment, magnetic patch 4 was relative mutual exclusions (on the contrary) with 6 magnetic directions across centre circle 2, equally another to organize across the magnetic patch 5 of centre circle 2 also be (on the contrary) of relative mutual exclusion with 7 magnetic direction; For strengthening the magnetic induction density of air gap between centre circle 2 and the both sides magnetic patch, magnetic patch adopts high performance rare earth permanent magnet ndfeb magnet, centre circle 2 adopts the soft magnetic material of high magnetic permeability, and the gap between centre circle 2 and the magnetic patch is keeping as much as possible little under the discontiguous prerequisite between lasso inboard and centre circle 2, the lasso outside and the magnetic patch; When the copper coil on the lasso outside being enclosed within centre circle 2 is switched on, direction of current in the copper coil in magnetic field, centre circle 2 both sides is opposite, and the direction in magnetic field, both sides also is opposite, that is to say, the current in wire of conductive coil 11 or 12 in magnetic patch 4 magnetic fields and the current in wire in magnetic patch 6 magnetic fields are reverse, and the magnetic direction of magnetic patch 4 also is opposite with the magnetic direction of magnetic patch 6.Like this according to describing the Amp that concerns between magnetic induction density, electric current and the Amp, the acting force that magnetic field, both sides gives conductive coil is along circumferencial direction also in the same way just, the amplitude of acting force is directly proportional with strength of current, and direction changes with sense of current.
Owing to the complete in a circumferential direction symmetric arrangement of two groups of conductive coils 11 and 12, therefore come the trend of Control current by the connection between described two groups of copper coil end lines, make that two groups of conductive coils 11 are opposite with the 12 lucky equal and opposite in direction of the force of periphery, the directions that produce in the magnetic field, and be all clockwise or be all counterclockwise, so just formed a magnetic field force pure torsion, its numerical value should equal one group of coil and produce the diameter that force of periphery sum multiply by centre circle 2 center lines in magnetic field, both sides.
Under the effect of above-mentioned magnetic field pure torsion, the above-mentioned module I that relatively rotates will rotate with respect to said fixing module II and axle system, and this causes described camber of spring to cause spring force.Because described a pair of spring symmetric arrangement in a circumferential direction, the power that therefore described a pair of spring produces is that equal and opposite in direction, direction are opposite, and is all clockwise or is all counterclockwise, has so also formed a spring force pure torsion.
Present second kind of scheme of brief description.This moment, magnetic patch 4 was that homophase is inhaled mutually with 6 magnetic directions across centre circle 2, same another group also is homophase suction mutually across the magnetic patch 5 of centre circle 2 and 7 magnetic direction, but since coil in magnetic patch 4 (magnetic patch 5) magnetic field current in wire and the current in wire in magnetic patch 6 (magnetic patch 7) magnetic field be reverse, so, the force of periphery that described conductive coil produces in magnetic field, both sides is reverse, the moment of torsion that produces of each the group coil force of periphery that should equal coil one side multiply by the width between two lateral coils like this, total and the magnetic field force pure torsion be exactly the moment of torsion sum that two groups of coils produce.
The invention still further relates to a kind of implementation method of electric reverse vibration generator, in conjunction with the description of front, this method mainly includes following steps:
Step 1 relatively rotates module and axle system is fixed together, and stuck-module is fixed on the shoring of foundation body by rigid support or elastic support.
Aforesaid axle system is exactly described here shoring of foundation body.Described rigid support refers to the mode that rigidly fixes.Described elastic support refers to the structure of utilizing elastic construction to fix, and this elastic construction, particularly thrum spring are also non-limiting certainly.
Reverse the vibration frequency electric signal that the electric signal load-on module produces each frequency range, such as, this vibration frequency can be taken as 800Hz.This electric signal utilizes the effect of electromagnetic force after being loaded on conductive coil 11 or 12, can make to relatively rotate the module setting in motion, and this motion is to realize with the mode of vibration that swings back and forth.
Reverse vibration generator drives axle system and begins vibration, and this vibration situation can be surveyed by the torsional oscillation sensor, obtains corresponding measuring-signal.
In axle system frequency measurement structure, torque sensor can also be set, by measurement, realize model analysis operation better to axle system to moment of torsion.
Reverse vibration frequency and amplitude (can characterize) that the electric signal load-on module loads according to data such as voltage that is loaded and strength of current, also need to transmit to signal processing module with signal operation processing capacity, signal processing module relies on this data, just can calculate easily and respectively reverse the electrical signal data frequency, pairing axle system amplitude situation.
During this, it is consistent that the amplitude of institute's loading data is fit to; Certainly do not limit yet.
Utilize the torsional oscillation sensor to come the amplitude situation of measurement axis system, if A, the B, the C three place's peak values that occur, so, the pairing frequency that applies of reversing the electric signal load-on module under this A, B, the C three place's peak condition, just corresponding the natural frequency of axle system is calculated very convenient, quick.
Utilize reverse vibration generator of the present invention, except can natural frequency, can also apply torque load, it is carried out long duration test, perhaps various exciter responses tests axle system in order to the measurement axis system.
Aspect long duration test, as an example, the ability of can the proof bar system bearing the dynamic loading moment of torsion for a long time.Such as: variator one end is fixed, and the other end connects with vibrator of the present invention, by vibrator simulation variator actual operating mode it is applied torque load.
Aspect the exciter response test, as an example, can the proof bar system for the reaction condition of various load excitations, investigate it and have or not abnormal conditions, or do not meet the demands.For example: connect with described vibrator in a manner described for clutch system, the various impact situations of simulated clutch are loaded it by vibrator, to investigate its response characteristic.
More than be the description of this invention, and unrestricted, based on other embodiment of inventive concept, also within protection scope of the present invention.
