Description
Technical field
The present invention relates to bodies of a motor car, and in particular to a kind of test-bed for testing door sash dynamic offset and test
Method.
Background technology
The dynamic sealing performance of arrangements for automotive doors be weigh automobile wind noise performance an important indicator and client it is most direct
The performance experienced.Car door dynamic sealing is related to inside and outside clamp bar sealing, sealing of the glass groove to glass, and sealing strip is to car door
Sealing etc..Automobile when running at high speed, vibrated back and forth, works as door sash by the normal direction of the opposite gusset of door sash meeting
When the spoke value of vibration is more than the amount of interference of window frame and caash bar, the sealing function of caash bar will fail.Tradition research dynamic sealing
Method be primarily upon the structure of sealing element itself, such as pass through the structure for optimizing clamp bar, glass groove and sealing strip and interference
Amount, to improve dynamic sealing performance." car door offset measurement fills in a kind of vehicle traveling process disclosed in CN103940393A
Put ", include point gear and recording mechanism, recording mechanism is fixed on vehicle side wall, and point gear is fixed on car door,
Pointer and recorder coordinate, by the beat of pointer into recorder input signal；It is by Liang Ge mechanisms, in vehicle operation
Middle record data, vehicle stop post analysis data, ensure that measurement accuracy and personnel safety.Main engine plants are seldom related to under dynamic
The offset of door sash metal plate is studied.The dynamic offset of door sash metal plate is quite heavy to the dynamic sealing of sealing strip
Will, when door sash metal plate is with respect to the gusset exterior normal direction amount of shifting, the amount of interference of door sash and sealing strip for door frame
It can become smaller, good dynamic sealing performance be kept to want when the amount of interference of door sash and sealing strip for door frame is less than sealing strip for door frame
During the minimum interference amount asked, sealing strip for door frame will be leaked with window frame mating surface, and interior wind noise is caused to become larger, causes Gu
Complaint of the visitor to wind noise.The control of the dynamic offset of door sash has internal car noise important influence, therefore, it is necessary to
Look for another way exploitation new test device and test method.

The intensity for the light that pixel array receives, and according to testing conditions Automatic Optimal）.
Processing system includes：Microtrak3（Microtrak3 be using triangle measurement technology come carry out displacement, distance,
Vibration and the precise measure system of Thickness sensitivity）.
Testing procedure：
Referring to Fig. 4, laser displacement sensor 10 is fixed on the X of test-bed on moving block 8, by laser displacement sensor
Electric power connection line is connected on electric pressure converter 15, the connection of the power supply of voltage converter and 220V, and by laser displacement sensor
10 DOL Data Output Line is connected on notebook 16；Notebook is opened, the laser head of laser displacement sensor starts to emit laser
Beam opens power supply and carries out relevant setting：It is " Normal " to set " Mode ", and " Gain " is " Auto ", and " Avg " is
" 250 Hz low pass filtering ", presses " Zero " button and laser winding degree is zeroed out；After pressing reset button,
Blue lamp beside button brightens, and shows in running order.
Adjust position of the Y-direction guide rail 4 in the dovetail groove below X direction guiding rails, make laser displacement sensor laser head and
Aluminium foil reflecting piece 14 is consistent in X-direction position.
Adjust positions of the X to moving block 8 in Z-direction guide rail 7 above and below kidney slot so that displacement sensor exists with reflecting piece 14
Z-direction keeps sustained height position.
X is made to be rotated to moving block 8 around X-direction, until laser beam emitting head and the aluminium foil reflecting piece 14 of laser displacement sensor
Surface near normal adjusts the position in Z-direction 7 kidney slot in Y-direction guide rail 4 of guide rail so that laser displacement sensor LTS-
The equilibrium distance 220mm of 200-100, then the emitting head of laser displacement sensor tests the outside testing range of car door and is
30mm, inside testing range are 10mm.
0 ° of deflection angle testing：It opens inner-outer circulation hole and allows air-flow normal through and closing air-conditioning.Pay attention in 0 wind speed, minimum
Air-conditioning is also opened in addition to proper testing when wind speed, arrogant wind speed and carry out contrast test, turn on the aircondition what car door was deformed with evaluation
It influences；It blows, the average data of " eyeball " display is recorded after wind speed stabilization, later using every 30km/h as a ladder
Increase wind speed, it is same that wind speed is waited to record evaluation data after stablizing until maximum wind velocity；
Deflection angle testing：After finishing, corresponding right+10 ° ,+20 °, -10 °, the tests of -20 ° of progress car door deformations, wind speed is similary
Increased with every 30km/h.After driver side car door deformation test finishes, the passenger side car door is similarly tested；
Test data inspection.
After all air speed datas are completed when any drift angle, wind speed is returned into 0 wind speed, while check that laser head is shown
Data whether back to zero, if error should be less than 0.2mm not as back to zero；If it exceeds 0.2mm, illustrates that laser head is being surveyed
Fixed not good position is changed during examination, then laser head is retightened to method.It is next in progress
Before a deflection angle testing, door outside is gently patted with hand, laser head to be helped to show back to zero, if display is unable to back to zero,
It is zeroed out twice by reset button.
