The violent oscillatory motion of amount, so as to accelerate the agings such as high polymer material, the active material of transducer, metal material, make its stress collection
The weakest link of middle part is exposed, and produces failure.As do not broken down in the stipulated time, according to current statistics and
The comparison result of test data, it can be determined that the reliability of the acoustic array and life-span.
After the completion of experiment, the middle taking-up from large-scale anechoic tank, by hermetically sealed can 100, exhaust outlet 12 and discharge outlet are opened
24, water inlet 23 is simultaneously closed off, the water in hermetically sealed can 100 is discharged by drainpipe 10.
Acoustic array 200 is simulated in real work using the reliability test of the present invention for acoustic array 200
The behaviour in service of environment, the reliability and service life for obtaining acoustic array 200 in actual working environment can be tested.It is described reliable
Property experimental rig is capable of the hydrostatic pressure of the working environment of adjustment control acoustic array 200, moreover it is possible to controls excitation component 5 to make acoustic array
200 excite lower operational vibration continuously high-power, moreover it is possible to the accelerated aging test of acoustic array 200 is carried out, can be in the short time
Acoustic array reliability and the examination of service life of more than 10 years is inside realized, data are accurately and reliably.The reliability test
To the result of the test of acoustic array 200 on the one hand to provide data supporting, the opposing party to the preventative maintenance of acoustic array 200 from now on
Face, technology guiding is provided for the reliability growth of later stage acoustic array 200.
The present invention can not only carry out electric stress accelerated test to acoustic array can also carry out hydrostatic pressure acceleration and temperature simultaneously
Accelerated test is spent, further shortens the experiment examination time.
As described above, we are illustrated fully according to spirit of the invention, but the present invention is not limited to above-mentioned reality
Apply example and implementation.The practitioner of correlative technology field can carry out different in the range of the technological thought license of the present invention
Change and implementation.
