摘要
针对商用车在加速行驶中车外噪声对城市环境带来的污染越来越严重,而目前的GB 1495-2002车外噪声标准试验方法不能较好地测量出商用车真实噪声值,因此,在该标准的基础上,对车外噪声标准的试验场地、档位选择、噪声修正以及试验方法等进行改进,通过前后两种试验的对此,得出改进后的加速行驶车外噪声测量结果更贴近实际,这对商用车加速行驶车外噪声标准的研究提供了一定依据。
In view of the increasingly serious pollution caused by the external noise of commercial vehicles to the urban environment during acceleration, the current GB 1495-2002 Standard Test Method of external noise can not better measure its real noise value. Therefore, the test site, gear selection, noise correction and test method of external noise standard are improved. Through two kinds of tests, it is concluded that the improved noise measurement results are closer to the reality, which provides a certain basis for the study of the external noise standard of commercial vehicles when accelerating.
