Through demand analysis, status analysis, and marine climatic characteristic analysis, a new thought of climatic type simulation was put forward, and the radiation with salt fog, salt crystal accumulation and internal corrosion were solved simultaneously. Through general design, module design, and integrated manufacturing, the acceleration test chamber for multifactor integrated marine climate simulationwas developed, which can apply light radiation, salt fog, temperature, humidity,and wind speed simultaneously. Test spectrum design and verification test was applied to evaluate the conformity to technical index, correlation, and acceleration. Verification result showed that in evaluation of critical parameters changes of materials,such as corrosion weight loss of metal, tensile strength degradation, and color and gloss change of organic coating, the multifactor integrated marine climate simulation and acceleration test technology has good correlation and high acceleration comparing with outdoor exposure test results of Wanning station.
