目的研究一种金属减振器的库房贮存寿命的实验室加速贮存试验验证方法。方法首先分析某型金属减振器的性能指标参数和贮存薄弱环节,然后设计并实施相关的加速贮存试验。通过对试验数据进行回归分析,获得金属减振器常温下的应力松弛关系式,进而开展金属减振器的加速贮存验证试验,验证其贮存后的性能指标参数能够否满足要求。结果根据验证试验的数据结果评估得出,某型金属减振器在常温库房贮存环境至少能达到15 a的贮存寿命。结论通过在实验室开展加速贮存试验,能够在短时间内验证金属减振器的贮存寿命,为金属减振器寿命评估工作提供了技术支撑。

Research on Accelerated Storage Validation Test Method of a Certain Type Metal Damper

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.
