| The work aims to establish an accelerated test method for storage-duty life of typical electromechanical products under complex environmental stress. Based on the analysis of the storage-duty life profile, environmental factors and base conditions of electromechanical products, the environmental factors for simulation and acceleration were selected considering the possible impact of environmental effects and accumulated damage on key components. According to the time sequence of environmental stress application and damage model, an accelerated test method was proposed, which comprehensively considered the effect of environmental stress on the life of electromechanical products during storage-duty, such as temperature, damp heat, salt spray, solar irradiation, temperature cycle, vibration, impact, etc. The accelerated test profile for storage-duty life of a typical electromechanical product under complex environment was established. The accelerated life test of electromechanical products under complex environmental stress fully considers the environmental stress experienced by electromechanical products during storage-duty, and can represent the accumulated superposition effect of various environmental stresses during storage-duty of electromechanical products to a certain extent. |
