摘  要:
近年来由于人机工程的发展,对作业条件的改善日益重视。本文运用“消去法”、“频谱分析法”及“相干分析法”识别出集材50拖拉机驾驶室主要噪声源,并对选用合理的降噪方法进行了分析。一、测试试验测试系统参照国家标准(GB871-83)《农业拖拉机噪声试验方法》以及国际标准ISO《农林拖拉机耳旁噪声测试方法》。测试场地的实测本底噪声低于50dB(A) (一)发动机噪声测试

摘  要:
In this study, main noise resource in CAB of the caterpillar skidding tractor 50 were identified by "elimination" and "spectrum analysis". According to analysed results, the multiple input/single output models with ear-side noise for output and other noise resources for input were respectively set up, programmed and calcutated by a computer to Solve the influence degrees of various noise resurces inputted on driver's ear-side noise. Some measures for reducing main resources were adopted, so that the value of driver's ear-side noise is decreased by 5.5dB(A). The restults can provide effective means for reducing the noise in the CAB.
