汽车整车在典型环境下大气暴露试验结果分析

Analysis of Complete Vehicle Atmosphere Exposure Test Results in Typical Environments

目的考核汽车整车在典型环境的耐候性。方法选取国内5个典型环境开展整车大气暴露试验,积累汽车的耐候性数据。结果获得了车体温度分布情况、整车的外观变化以及运行使用性能方面的环境试验数据。结论通过对试验结果分析显示,在各种典型气候环境条件下,车体温度的分布情况及整车外观、内外饰材料的腐蚀老化特征具有明显差异,为了能够全面考核汽车的耐候性,需要综合考虑各种气候环境的不同影响。

Objective To evaluate the weather durability of complete vehicle in typical environments. Methods The complete vehicle atmospheric exposure test was carried out in five selected inland typical environments to accumulate data for complete vehicle weather durability. Results Distribution of vehicle body temperature, and change of complete vehicle appearance, as well as the operation performance environmental test data were obtained. Conclusion The test results revealed that the distribution of vehicle body temperature, the appearance of complete vehicle, and the corrosive aging characteristics of the interior ＆ exterior material were obviously different in various typical environments. It is necessary to consider the effects of different climates in comprehensive evaluation of vehicle weather durability.
