摘要
分析了GB 1495《汽车加速行驶外噪声限值及测量方法(中国第三、四阶段)》(报批稿)与ECE R51/03法规《就噪声方面批准四轮及四轮以上机动车的统一规定》在术语定义、测量仪器、测量环境、测量车辆准备、测量挡位、测量工况和测量结果处理7个方面存在的主要差异。采用轻型汽车和重型汽车样车,依据两项标准法规分别进行测试,获取测量结果的差异性,为车外噪声试验及相应的技术开发提供参考。
This paper analyzes the differences in testing methods considering 7 aspects, i.e. the terms and definitions,test equipment,test conditions,test vehicle preparation,test gears,test cycles and test data processing between the GB 1495 Limits and Measurement Methods for Noise Emitted by Accelerating Motor Vehicles(China Ⅲ,Ⅳ)(to be approved) and the UN Regulation No. 51/03 series Uniform Provisions Concerning the Approval of Motor Vehicles Having at Least Four Wheels with Regard to Their Sound Emissions. The light-duty and heavy-duty prototype vehicles were tested according to the GB 1495 standard and the ECE R51/03 respectively and the differences in testing results were analyzed. The paper provides a reference for vehicle noise testing and related technical development.
