基于自然暴露试验的乘用车耐候性研究

摘要

在我国海南琼海典型湿热大气环境下对自主品牌和国外合资品牌乘用车进行了长期自然暴露试验。基于自然暴露试验结果，论述了我国乘用车服役环境，总结了我国乘用车主要存在的耐候性失效，以及与国外合资品牌乘用车耐候性技术的差距，并对我国乘用车耐候性研究发展提出了一些建议。%The domestic brand and foreign joint venture brand passenger cars were studied through long-term natural exposure test under typical damp-heat environment in Qionghai, Hainan Province. Based on natural exposure test results, this paper studies the service environment of passenger car, summarizes the main weatherability failure of domestic brand, the distance between foreign joint brand, and gives some advices to domestic brand passenger cars development.
