Vibration direction and time

 vibrate in one direction for at least 10min

Control point

should be selected in the fixture or shaking table surface near the maximum stiffness of the product, large equipment can use multi-point average control

Monitoring point

the monitoring point should be selected in the key part of the product under test, so that the root mean square acceleration response does not exceed the maximum allowable design (grms=6.06)

Installation requirements

The specimen is rigidly connected to the shaking table, and the product with shock absorber should remove the shock absorber for test

Performance check

Power-on test during vibration, all performance indicators should meet the technical requirements specified in the design document.In case of failure, it is allowed to repair.When the acceptance test is carried out after repair, the spectrum value should be reduced to 0.01g2/Hz, grms=3.03, and the specimen should be vibrated in the direction most afraid of vibration for 10min

Temperature cycle

Temperature range

Power-on test

-35±3℃ ~ +52±2℃

Rate of temperature change

Temperature rise

10℃/min

Cooling

10℃/min

Cycle times

10 times, should ensure that the last 2 cycles without fault, if the fault occurs in the last 2 cycles, after repair, need to make up 2 trouble-free cycles

Cycle time

One cycle time is 4h, one cycle includes temperature rise → temperature stay → cooling → temperature stay → temperature rise

High and low temperature residence time

the residence time depends on the heat capacity of the specimen. Based on the principle of product thermal or cold permeability, the internal temperature of the specimen is maintained for 5min after reaching stability

The requirements of the product under test

general temperature cycle test with the whole machine, should be as far as possible to open the cover

Check and repair

 power test equipment, in each temperature cycle, after the test to confirm that the equipment is fault, can carry out the next temperature cycle

Drenching requirements

Drenching is carried out with the whole equipment

Sports car

Sports cars go with the whole device

If the product does not do road transport test, you can use the simulation transport table for indoor transport simulation test, that is, sinusoidal cyclic vibration test for product identification

The requirements of the simulated transport table test are as follows

Test conditions

Frequency

 5Hz ~ 200Hz

Amplitude

 5Hz ~ 7Hz

Amplitude 12mm ~ 8mm

7Hz ~ 200Hz equal acceleration 1.5g

Vibration test condition allowable deviation is the same as broadband random vibration test

Direction

vertical axle direction and side;Orientation: vertical and lateral to the axle

Cycle time

log-scan 5Hz ~ 200Hz ~ 5Hz, 12min per cycle;When the resonant frequency of the specimen is measured below 5Hz, the test frequency can be extended to 2Hz, 2Hz ~ 200Hz ~ 2Hz scanning, scanning time should be 15min.The vibration time in each direction is 90min

After transportation test, check whether there is damage and structural loosening phenomenon, carry out technical index inspection, should meet the design requirements
