摘要
介绍国家标准中汽车动力总成噪声测试对声学测试环境的要求,提出汽车动力总成噪声实验室建设的指标。重点介绍一汽技术中心在1998年技改建设项目中利用原有的实验室空间,设计和建设汽车动力总成半消声室的情况。
The requirement of acoustic test environment of automobile powertrain noise test in National Standard was introduced. Some indexes for construction monitoring of automobile powertrain noise laboratory were put forward. The design and construction of automobile powertrain semi-anechoic chamber using used laboratory room, as a technology reform project supported by FAW R＆D Center in 1998, was emphatically introduced.
