|
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 |

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 |
|||||||
