Description
Technical field
The invention belongs to field of measuring technique, and in particular to it is a kind of provide low-voltage high speed be used for accelerometer test
Motor.
Background technology
Accelerometer is the instrument for measuring acceleration.When object by dynamic loading will be produced acceleration, due to dynamic loading
It is difficult accurate measurement in engineering, can first measures acceleration and calculate dynamic loading again.Meanwhile, by the instantaneous grasp to acceleration,
Locus and the movement locus of object can also be further known to.As it is to be understood that where each instantaneous aircraft, rocket and naval vessels
Locus, can continuously measure its acceleration by inertial navigation (see gyropanel inertial navigation system), then by product
Partite transport is calculated and obtains velocity component, and integration obtains the position coordinates signal in a direction again, and the instrument of three coordinate directions is surveyed
Amount result just integrates curve movement and provides the locus where per instantaneous ROV.
But the solution that the detection of prior art accelerometer self performance has not been found also.Particularly to some
During special occasion, such as field work, high rotating speed (at least 1000r/min) how is provided with low-voltage DC, at present or skill
Art blank, in addition prior art also be difficult to meet the stability requirement of test platform, usually require that in the high rotating speed bars of 1000r/min
The bounce of part lower surface is less than 0.01mm, and these problems constrain the accurate detection to accelerometer self performance.
The content of the invention
In view of this, it is an object of the invention to provide a kind of low-voltage high speed, stability it is good be used for accelerometer test
Motor, it is possible to resolve the problem of stability that exists during prior art operation in the wild is poor, rotating speed is low.
The purpose of the present invention is achieved through the following technical solutions：
The motor tested for accelerometer, including motor body, in addition to test platform, the motor body include electricity
Casing, the stator being detachably fixed with motor casing and the rotor for being arranged on bore of stator center, the rotor is in bore of stator
One end coordinates with stator in uniform gap, and the other end stretches out motor casing and the central integral of test platform is set, and in extension
Position is by double row angular contact bearing and the rotatable fixation of motor casing, and the test platform is circular pan-like structure, the motor casing
Test platform one end is provided with adpting flange and closure, the adpting flange is connected solid with closure by fastener
It is fixed.
Further, the flatness of the top surface of the test platform is less than 0.005mm.
Further, multiple acceleration are evenly arranged with same diameter circumference in the plane of the top surface of the test platform
Degree meter fixed bit.
Beneficial effects of the present invention：
The present invention is wholely set by rotor and test platform can improve the rigidity of test platform, and it is steady that enhancing is run
Property, meanwhile, larger radial load and axial load can be born by double row angular contact bearing, so as to limit radial and axial position
Move, can further improve stationarity.Enable the invention to realize and reached using 24 volts of low-voltage DCs as power drives
The design object that accelerometer performance is accurately tested is run and carried out to 1000r/min high-speed smooths.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The present invention target and other advantages can be realized by following specification and
Obtain.
Brief description of the drawings
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing the present invention is made into
The detailed description of one step, wherein：
The structural representation for the motor that Fig. 1 tests for the present invention for accelerometer；
Fig. 2 is Fig. 1 top view.
Embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.It should be appreciated that preferred embodiment
Only for the explanation present invention, the protection domain being not intended to be limiting of the invention.
As shown in Figure 1 and Figure 2, the present embodiment is used for the motor that accelerometer is tested, including motor body 1 and test platform
2, motor body 1 includes motor casing 3, stator 4 and rotor 5, and stator is detachably secured in motor casing, and rotor is arranged in stator
Chamber center, rotor coordinates in one end of bore of stator and stator in uniform gap, i.e., with certain electric field space, that is, electric energy
The electromagnetic field space changed with mechanical energy, it is equal it is magnetomotive in the case of, gap is bigger, and magnetic resistance is also bigger, is formed
Magnetic field intensity is also weaker, and the other end of rotor stretches out motor casing and the central integral of test platform is set, can strengthen rigidity water
It is flat, it is to avoid prior art has the defect that rigidity is small, running stability is poor using motor shaft scheme, while the present embodiment is stretching out
Position can bear larger radial load by double row angular contact bearing 6 and the rotatable fixation of motor casing, double row angular contact bearing
And axial load, so as to limit the both sides axial displacement of axle, the stationarity of rotor operation, the present embodiment can be further enhanced
