| Abstract: |
| The work aims to compare the solar simulation test based on DIN 75220 standard and the outdoor exposure test in Hainan, China. With a certain vehicle and PC and PS standard plates as the research objects, the results of micro-environment of typical parts of the vehicle, failure behavior of typical parts of the vehicle and temperature-corrected solar radiation in natural exposure test and solar simulation test based on DIN 75220 standard were compared and studied. The correlation between the statistics in the two test methods was analyzed. By combining the color difference of paint parts, the change results of gaps between interior and exterior trims and the typical failure problems of key components under the two methods, a customized solar simulation test cycle suitable for simulating the typical hot-humid natural environment in Hainan, China was proposed. According to the research results, a large cycle of complete vehicle solar simulation test based on DIN 75220 standard can reflect about 80% of the failure problems that occur in 3-6 months during humid-hot natural environment exposure test. The damp climate cycle test in DIN75220 standard can better simulate the humid-hot natural environment in Hainan, China, and 35 damp climate cycles can be used to simulate the natural exposure of complete vehicle in Hainan for 1 year. |
