| When the underwater weapon reaches the specified storage period, how to reevaluate the status and extend the service life by means of maintenance and replacement, further play the benefits of equipment. This paper expounds the research status of life extension of underwater weapons firstly, then the effects of high temperature, low temperature and alternating temperature on the product composition and failure mechanism were analyzed in detail. On this basis, taking torpedo as an example, the design flow chart of storage life accelerated test is put forward. Various factors is evaluated comprehensively to determine the stress type of accelerated storage life test, torpedo temperature acceleration factor, temperature accelerated test stress and accelerated test time, then, the flow chart of storage accelerated life test is established. The test scheme shall be formulated according to the determined relevant elements to clarify the storage failure and storage life termination criteria. The record data, failure judgment and test conditions are comprehensively recorded, and the test conclusions and improvement suggestions are put forward, which provides basis support for equipment life determination index confirmation and life extension measures formulation. |
