【摘要】為分析汽車內(nèi)外飾高溫驗證中高溫環(huán)境臺架試驗與高溫適應(yīng)性實車試驗結(jié)果的差異,通過對轎車、SUV車型開展高溫環(huán)境臺架試驗和實車環(huán)境測試,從溫度、輻照度、風(fēng)速方面分析二者的差異,發(fā)現(xiàn)主要差異體現(xiàn)在輻照度方面,并提出在環(huán)境艙內(nèi)加裝弧形燈架、側(cè)邊輻照等方式縮小差異,以提高臺架試驗的準(zhǔn)確性。

【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

夏季高溫環(huán)境下,汽車內(nèi)外飾是輻照直射區(qū)域,也是用戶高感知區(qū)域,為避免高溫導(dǎo)致的變形等外觀故障,須針對汽車內(nèi)外飾開展高溫環(huán)境驗證。(剩余3380字)
