Part and work of electromagnet also receive first group of laser pick-off pipe LQ1, second group of laser pick-off pipe LQ2 and the output of amesdial 140
Signal.
Wherein, the dynamic iron core of above-mentioned electric magnet can be conflicted at the friction sensor of tested power drive assem when stretching out
On, thus, it is possible to the friction sensor utilizing the dynamic iron core of electric magnet to resist tested power drive assem moves and exports timing
Control signal, with simulation at the rolling wheel wear of the tested power drive assem of aircraft hold to after to a certain degree, friction sensor quilt
Counter is pushed down and is stopped operating, and verifies that whether working properly tested power drive assem internal circuit is, and is measured by control panel
The time of tested power drive assem power-off it is held down from friction sensor.The up and down motion track of above-mentioned block 123 passes through
First laser optical path and the second laser optical path, thus, it is possible to utilize the up and down motion and two of block 123 assemble to laser send out
Penetrate pipe and laser pick-off pipe produces timing control signals.Above-mentioned amesdial 140 be arranged on gripper shoe 120 and support stand 100 it

Moving data and show at amesdial 140, the cam utilizing amesdial 140 to measure tested power drive assem accurately rises act
Highly.The output shaft of above-mentioned tested power drive assem is coupled with outside dynamometer machine by the anti-axle 190 that drives, thus, it is possible to sharp
Reverse torque loads is loaded so that tested power drive assem motor lock-rotor, tested power drive group with outside dynamometer machine
The power-off because of overtemperature protection of the motor of part, after torque loads unloads, the motor internal temperature of tested power drive assem recovers
Normally and again task, the time that time of thermal tripping spent by the motor of this process and motor is resumed work all surveyed by control panel
Amount.
Fig. 2 shows a kind of physical circuit form of above-mentioned control panel, its operation principle and of the present utility model from
The occupation mode of scattered signal measurement apparatus is as follows:
Before test, driving rolls and the pedestal of tested power drive assem are all removed, in the output shaft at driving rolls
Hexagonal end connects the anti-outer-hexagonal termination driving axle 190, fixes tested power drive assem to supporting platform by steady pin 110
Frame 100；SW9DIR A or the SW11DIR B point driving switch of pressing control panel, tested power drive assem connection exchange 115V,
400Hz and 28VDC unidirectional current, internal motor rotates and passes through gear reduction band moving cam and rises act, cam driven roller
121 so that roller 121 moves downward, and finally drive block 123 to move downward, lift when tested power drive assem cam rises
After completing, block 123 also stop motion, and stop be arranged on the laser pick-off pipe in 160 times grooves of left column, sharp because not receiving
Light, laser pick-off tube voltage output 0V；When cam rises and lifts beginning, Q8 pipe does not blocks nethermost laser pick-off at block 123
Guan Qian, is constantly in conducting state, and LS5 relay is constantly in Guan Bi, No. 3 contacts of LS5 relay and No. 4 contact conductings, convex
Wheel rises when lifting timer, and after cam liter act completes, Q8 pipe turns off, LS5 relay because laser pick-off pipe output 0V voltage
Power-off, No. 3 contacts of LS5 relay and No. 4 contacts disconnect, and cam rises lifts timer stopping timing, and this process completes tested dynamic
Power drives assembly cam to rise and lifts timing.
Pressing SW12STOP point driving switch, tested power drive assem power-off, cam falls after rise；Spring supporting post 130 discharges
Decrement, promotes the block 123 in gripper shoe 120 to follow cam closely and moves upwardly together, before block 123 reaches initial position,
Being positioned at the laser pick-off pipe of groove on left column 160, because not receiving laser, laser pick-off tube voltage output 0V, Q6 manage always
In the conduction state, LS6 relay is constantly in Guan Bi, No. 3 contacts of LS6 relay and No. 4 contact conductings, and cam declines timing
Device timing, after cam has fallen after rise, on left column 160, the laser pick-off pipe in groove receives laser and exports 5V voltage, and Q6 manages
Turning off, LS6 relay power-off because of laser pick-off pipe defeated 5V voltage, No. 3 contacts of LS6 relay and No. 4 contacts disconnect, under cam
Fall timer stops timing, and this process completes tested power drive assem cam is declined timing.
Electromagnet base 170 is provided with electric magnet, by the dynamic iron core of the IDLER LOCK on-off control electric magnet of control panel
Jack-up, resists the friction sensor motion of tested power drive assem, during tested power drive assem energising work, is arranged on C
The Hall current sensor U4 of phase senses alternating current, No. 5 pin output high level at Hall current sensor U4 > 2.6V, warp
Comparator U7A exports+28V voltage more afterwards, starts friction timer timing；After friction sensor stop motion, tested power
Driving component internal control circuit to disconnect external power source to access and stop operating, Hall current sensor U4 is because sensing is less than exchange
Electric current, at No. 5 pins output 2.5V voltages of Hall current sensor U4, through comparator U7A carry out voltage ratio relatively after, than
No. 1 pin output 0V voltage of relatively device U7A, friction timer stops timing；This process is tested dynamic at aircraft hold for simulation
Power drives the rolling wheel wear of assembly to after to a certain degree, and parts automatically power off protection and do not rise act.
The anti-axle 190 that drives is connected with the interior hexagonal axis of tested power drive assem by outer-hexagonal, by outside dynamometer machine
Load reverse torque loads and make tested power drive assem motor lock-rotor, when motor lock-rotor, Guan Bi switch DRIVER
LOCK, motor now is the most just by stall, and internal temperature is not reaching to the temperature of overtemperature protection, and Hall current sensor U4 is still
Sensing alternating current, in No. 5 pins output of Hall current sensor U4 more than 2.6V level, through comparator U7A relatively after than
No. 1 pin output 28V voltage of relatively device U7A, during stall timer；When, after stall a period of time, internal temperature reached
The temperature of Thermal protection, the power-off because of overtemperature protection of the motor of tested power drive assem, now Hall current sensor U4 sensing
Less than alternating current, force No. 1 pin voltage reversion of comparator U7A, export 0V voltage, stop during stall timer, compare
No. 6 pins output 2.5V, No. 5 pin reference voltage 2.6V of device U7B, through comparator U7B relatively after No. 7 of comparator U7B
Pin output high level, starts recovery timer timing；After torque loads unloads, inside the motor of tested power drive assem
Temperature begins to cool down, and normally works through recovering after a while and again, and Hall current sensor U4 senses alternating current again, suddenly
No. 5 pins outputs of your current sensor U4, more than 2.6V level, feed back to No. 6 pins of U7B, through U7B relatively after export 0V,
Recovery timer stops timing；This process completes the measure of time that thermal tripping crossed by motor and motor is resumed work.
Amesdial 140 is measured tested power drive assem cam accurately and is risen the height lifted, by tested power drive
The cam of assembly is connected with roller 121, drives amesdial 140 to move, produces displacement data and show at amesdial 140.
This utility model is not limited to above-mentioned detailed description of the invention, according to foregoing, according to the ordinary skill of this area
Knowledge and customary means, without departing under this utility model above-mentioned basic fundamental thought premise, this utility model can also be made
The equivalent modifications of other various ways, replace or change, all fall among protection domain of the present utility model.
