【摘要】为分析汽车内外饰高温验证中高温环境台架试验与高温适应性实车试验结果的差异，通过对轿车、SUV车型开展高温环境台架试验和实车环境测试，从温度、辐照度、风速方面分析二者的差异，发现主要差异体现在辐照度方面，并提出在环境舱内加装弧形灯架、侧边辐照等方式缩小差异，以提高台架试验的准确性。

【Abstract】In order to analyze the difference between the high-temperature environment bench test and the real vehicle test results of high-temperature adaptability in the high-temperature verification of automobile interior and exterior trims， the high-temperature environment bench test and real vehicle environment test are carried out for passenger vehicle and SUV， and the differences are analyzed from the aspects of temperature， irradiance and wind speed. The results show that the main differences exist in irradiance， and it is proposed to install arc-shaped lamp support in the environment chamber and apply irradiance to the sides to reduce the differences， and thus enhance correctness of bench test.

1 前言

夏季高温环境下，汽车内外饰是辐照直射区域，也是用户高感知区域，为避免高温导致的变形等外观故障，须针对汽车内外饰开展高温环境验证。（剩余3380字）
