Reach intelligent pressure control value；When shutdown acts progress, whether barostat 7 makes sealing air pressure reach wink before completion of closing the door
When pressure value.
Inflation/deflation noise: the inflation/deflation speed of sealing joint strip is directly proportional to the noise of generation, during statistics inflation/deflation
Noise situation, and the excessively high situation of noise whether often occur, the adjustable inflation/deflation speed of door sealing regulating system with make an uproar
Balance between sound.
As shown in figure 5, pressure value is obtained by repetition test in driving high-voltage value and stop, test process is as follows:
Driving high-voltage value: capacitance sensor 5 is attached on sealing joint strip, closed door, is gradually increased by barostat 7
Big sealing atmospheric pressure value, when capacitance reaches certain default value, (default value can be obtained by conversion, such as need high pressure conditions of driving a vehicle
When sealing joint strip fitting area increases N% (such as 50%) than conventional seals adhesive tape, then corresponding capacitance increases to conventional seals
The N% (such as 50%) of adhesive tape jointing capacitance) when, driving high-voltage value is set by sealing atmospheric pressure value at this time.
Pressure value in stop: capacitance sensor 5 being attached on sealing joint strip, closed door, and barostat 7 incrementally increases close
The sealing air pressure of seal strip, when capacitance reaches certain default value, (default value is traditional adhesive tape jointing capacitor that test obtains
Value), pressure value in stop is set by sealing atmospheric pressure value at this time.

Any door closing speed in reasonable interval, car door can normal switching-offs；
As shown in fig. 7, this rack automatically testing automobile minimum door closing speed, process are as follows:
1, mechanical arm 3 and door external-open handle are flexibly connected, rack switch door sensor 6 is arranged in car door and is delayed
It rushes on the binding face of rubber plug and side wall；
2, during closing of the door, the shutdown closed the door with a predetermined door closing speed is started letter by vehicle behavior simulator 1
It number is sent respectively to data logger 2 and mechanical arm 3, data logger 2 records the door closing speed that vehicle behavior simulator 1 transmits
Signal, mechanical arm 3 push car door to execute shutdown and act with default door closing speed；Closing of the door to promote before extreme position (
The pre-determined distance such as position 5cm before the position that car door will close, promotes preceding extreme position as mechanical arm 3) when, mechanical arm 3 stops
It only runs, car door is run by self inertia；Rack switchs door sensor 6 and car door is not turned off signal or is turned off signal transmission
To vehicle behavior simulator 1 and data logger 2；In car door opening process, mechanical arm 3 pulls open car door by traction rope；
Above-mentioned preset door closing speed can be obtained by binary search, and process is as follows: vehicle behavior simulator 1 controls machine
Tool arm 3 makes car door close the door with the door closing speed of 2m/S, if car door can close (2m/S, which is substantially all, to close), next time
Door closing speed is 1m/S, if car door can close, door closing speed next time is 0.5m/S；If car door cannot close, next time
Door closing speed is 1.5m/S, and door closing speed is in there are the section intermediate value of minimum door closing speed next time in a word, until speed of closing the door
Interval convergence is spent to range less than 0.1, and taking closing velocity section peak is the car door door closing speed of this test, above procedure
N times are repeated, n times mean value are taken, as car door door closing speed；
This test-bed and test method are equally applicable other intelligent sealing joint strips except door sealing regulating system
