In order to solve the problem of functional degradation, performance degradation, and reliability reduction during the storage of weapons and equipment, the accelerating life evaluation method of equipment under multi-stress conditions is studied. The basic concepts and research significance of equipment storage life are briefly introduced. The research status of storage life prediction work at home and abroad is introduced in detail. The key link of storage life assessment-multi-stress acceleration model is analyzed, and the problems existing in the current acceleration model research field are proposed. The direction of development has been forecasted.
