| Abstract: |
| The accelerated storage validation test method of a certain type metal damper is investigated to dual with the real storage life level. Firstly, the performance parameters and storage weakness of a certain type metal damper are investigated and the accelerated storage test of the metal damper is designed and carried into execution. Secondly, the stress relaxations function of the metal damper in normal temperature is obtained by linearization fitting to the test data.Finally the accelerated storage validation test the metal damper is carried out to work over the performance parameters status after long term storage. The storage life of a certain type metal damper in normal storeroom is at least 17 years according to the evaluation of the test results. The storage life of a certain type metal damper can be validated in little duration by the accelerated storage validation test in laboratory, which is the prominent evolvement to the storage life research and evaluation of the metal damper. |
