摘　　要：根据GB 16169-2005《摩托车和轻便摩托车加速行驶噪声限值及测量方法》,对大排量摩托车在不同气候条件下进行了加速噪声实验,研究温度、大气压力等气象条件对摩托车加速噪声测试结果的影响。应用傅立叶变化处理加速噪声数据,采用三分之一倍频程法对2、3挡的左右侧加速噪声频谱进行分析,研究加速噪声在各个频率段的能量分布情况,针对摩托车加速噪声特性,对测试方法提出了改进意见。According to GB 16169-2005 "Limit and measurement method of noise emitted by accelerating Motorcycles and Mopeds", the accelerating noise experiments of large displacement motorcycles under different climatic conditions are carried out. The effects of temperature and atmospheric pressure on the accelerating noise of motorcycles are studied. Fourier transform is used to analyze accelerating noise data, and one third octave method is used to analyze the spectrum of acceleration noise on the left and right sides of the second and third gears.

关 键 词：加速噪声 温度 大气压力
