| 中文摘要: |
| 为了对比DIN 75220标准阳光模拟试验与我国海南户外暴露试验，以某型汽车整车和PC、PS标准板为研究对象，对自然曝晒试验和基于DIN 75220标准的整车阳光模拟试验中汽车典型部位微环境、汽车典型部件失效行为以及温度校正太阳辐射量的结果进行了对比研究。分析了2种试验方法中各统计量间的相关关系，进一步结合2种方法下的油漆件色差、内外饰件间缝隙变化结果以及关键部件典型失效问题，提出了适合用于模拟我国海南典型湿热自然环境的定制化阳光模拟试验循环。研究结果表明，基于DIN 75220标准的1个周期整车阳光模拟试验可以反映约80%的湿热自然环境整车曝晒试验3~6个月出现的失效问题。DIN 75220标准中，潮湿气候循环试验可以较好地模拟我国海南湿热自然环境，35个潮湿气候循环可以模拟海南整车自然曝晒1 a。 |

| 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. |
