摘要
针对联合收割机进行收割作业时存在振动大噪声高的问题,以谷缘牌联合收割机为研究对象,运用振动速度测量方法和声强测量方法,对该联合收割机进行部件表面辐射噪声源识别的研究,获得了各主要噪声源的大小排列,并对联合收割机驾驶员耳旁噪声进行了比对测试。
According to the large vibration and high noise problems of combine harvester in the working process, an experimental study on surface acoustic source identification with the combine harvester of Guyuan was presented by =ing the surface vibration method and the acoustic intensity method. The ranking of the noise sources was obtained on the basis of their individual contribution to the overall noise of the combine harvester of Guyuan. The comparison test on the noise of the driver＇s ear in the seat of Guyuan combine harvester was conducted.
