英文摘要:

Marine natural environment acceleration testing technologies serve as critical foundations supporting the development of marine equipment. This paper systematically analyzes the accelerated failure mechanisms of materials and equipment under coupled marine environmental factors including physical impact, chemical corrosion, and biological fouling, as well as the main Marine natural environmental test technology. A novel fully-immersed dynamic acceleration test method based on seafloor platforms is proposed. By deploying long-term continuous operation platforms and innovatively integrating in-situ stress enhancement techniques such as depth gradient pressure cycling, nutrient-release bio-stimulation, and micro current electrochemical biasing, the experimental cycle is significantly shortened while preserving authentic failure pathways. An environmental compensation life assessment model is established. Compared with traditional laboratory simulations, this method overcomes limitations in environmental multi-factor correlation, providing an efficient solution for reliability testing of deep-sea equipment. The research findings offer reference for the marine testing system development.
