Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
It is shown in Figure 1 the utility model discloses a kind of vibrating motor performance testing device, including test board 11, with
Acceleration transducer 12 that the test board is fixedly connected, the power supply circuit 13 for providing power supply for the vibrating motor 15,
Process chip 14 for handling the acceleration information that the acceleration transducer is obtained.
Acceleration transducer 12 is fixedly installed on 11 on test board so that with test board phase can not occur for acceleration transducer
To motion.Fixed form can be welded and fixed, fixed by screw, mode, certain acceleration sensing are fixed etc. by glue
Device and test board can also be integrally formed.
Vibrating motor 15 and acceleration transducer 12 are located at the homonymy of test board 11, and are arranged at the center of test board,
Vibrating motor is connected by wire with power supply circuit 13, and is vibrated under the driving for the alternating voltage that power supply circuit is provided, vibration
Power passes to the position of centre of gravity of test board, and test board is not in twisting, and generally translational motion can accurately reflect oscillator
Indeed vibrations, because acceleration transducer and oscillating plate do not produce relative motion, therefore obtained measured by acceleration transducer
Acceleration be test board acceleration.The utility model supports the vibrating motor of test to include linear vibration motor and non-thread
Property vibrating motor.
Test board uses light material, and quality not should be greater than vibrating motor more than 10 times, and quality should try one's best close to vibration horse
The quality reached.If the quality of test board and acceleration transducer is identical with vibrating motor, when vibrating motor vibrates, acceleration is passed
The acceleration that sensor measurement is obtained is roughly the same with the acceleration of vibrating motor.Circular test board can be used in test board, due to circle
The quality that shape beta version is distributed everywhere is centrosymmetric distribution relative to center of gravity, and when vibrating motor vibrates, circular test board will not
Twist, generally translational motion, can accurately reflect the indeed vibrations of oscillator.It is of course also possible to use other moulding
Test board, but vibrating motor must be positioned in the center of gravity of the oscillating plate.
Acceleration transducer is generally by part groups such as mass, damper, flexible member, sensing element and suitable tune circuits
Into.Acceleration transducer, by the measurement to inertia force suffered by mass, is obtained in accelerator using Newton's second law
Acceleration magnitude.According to sensor sensing part classification, condenser type, inductance can be used in the acceleration transducer in the utility model
Formula, strain-type, pressure resistance type, piezoelectric type.
Acceleration transducer is fixed together with test board, and test board produces relative motion under vibrating motor vibration, plus
The acceleration that velocity sensor is obtained is the acceleration of test board, and following relation F=ma is provided according to Newton's second law, its
In, F is bonding force suffered by object, and m is mass of object, and a is the acceleration of object this moment, and the power of vibrating motor and test board is
Relative size is identical, therefore the acceleration of vibrating motor is multiplied by vibrating motor equal to the acceleration that acceleration transducer is obtained
Quality again divided by test board and acceleration transducer quality sum result.
In order that acceleration transducer more accurately measures the acceleration of test board, it is necessary to which acceleration transducer edge is vibrated
The direction of vibration of motor is set, i.e., acceleration transducer is located on the extended line that the oscillator of vibrating motor moves reciprocatingly.
Further improvement is made to fixed position of the acceleration transducer on test board at this, acceleration transducer is with shaking
Space is provided between dynamic motor, for avoiding vibrating motor from being contacted in vibration with acceleration transducer.In actual test, survey
Test plate (panel) produces relative motion in the reaction force of vibrating motor, if vibrating motor comes in contact in vibration with acceleration transducer
Collision, the then acceleration that acceleration transducer can be caused to obtain is inaccurate, causes the result that control chip is obtained to there is error, because
This, acceleration transducer is separated with vibrating motor, it is to avoid both contact-impacts in vibration processes.
In a kind of specific embodiment, test board, acceleration transducer and vibrating motor gross weight are 100g, now
Test board and acceleration transducer gross weight and vibrating motor weight are roughly equal, when vibrating motor vibrates, acceleration sensing
Device also it is measurable go out the vibrating motor same order of magnitude acceleration, it is to avoid test board and acceleration transducer gross weight are vibrations
The several times or decades of times of motor weight, when vibrating motor vibrates, the small situation of acceleration information that acceleration transducer is obtained.
Certainly, in actual test, test board, acceleration transducer and vibrating motor gross weight can be other values, but should be with shaking
Dynamic motor weight belongs to the same order of magnitude.
When test board even density can ensure that the oscillator of vibrating motor moves reciprocatingly, left and right acceleration is identical, certainly
Weight that can according to actual needs with acceleration transducer, is adjusted to test board density so that vibrating motor is along direction of vibration
The weight of both sides is identical.
In another specific embodiment, referring to shown in Fig. 2 and Fig. 3, test board 11 is tested for the circular of even density
Plate, vibrating motor 15 is located at the circle centre position of circular test board, and the oscillator of vibrating motor and circular test board center of gravity are in same lead
