摘要
参照ISO 362、ECE R51、GB 1495-2002标准中汽车整车噪声测试对声学测试环境的要求,按照GB6882-1986、ISO 3745-2003标准和实际使用需求提出国家汽车质量监督检验中心(襄樊)汽车整车半消声室建设的指标。实验室建成后通过中国计量科学研究院鉴定测试,达到设计要求。详细介绍汽车整车半消声室的设计方法、建设情况和鉴定结果。
The acoustic environmental requirements for whole-vehicle noise testing according to the ISO 362, ECE R51, and GB 1495-2002 standards are introduced. Referring to the national and international standards such as GB 6882-1986 and ISO 3745-2003 and considering the requirements in actual usage, some indexes of the whole vehicle＇s semi-anechoic chamber construction are proposed for the National Automobile Quality Supervision Test Center （NAQSTC） in Xiangfan. The laboratory for the testing in the NAQSTC has been appraised by China＇ s Institute of Metrology. The detail of the design, construction and the appraisement of the whole vehicle semi-anechoic chamber is introduced.
