摘　　要：为研究拖拉机振动对驾驶员舒适性的影响,试验测试了某型号拖拉机在标准较粗糙路面上以不同速度行驶时驾驶员处的振动特性,使用功率谱密度(PSD)曲线及"疲劳-降低工效界限"曲线对该振动进行了评价,结果显示水平方向及垂直方向的谱峰值频率在低频范围内集中在10 Hz以下,对驾驶员舒适性的影响明显,工作约1 h后驾驶员工效降低。To research tractor vibration influence on driver＇ s comfort,tests of a tractor running on standard rough road in different speeds were carried out. PSD curves and ＂fatigue-work efficiency decrease limit＂ curves were applied to appraise the vibration. The results show that in low frequency range, the peak values of the spectral are within 10 Hz, apparently, and this influences the driver＇s comfort obviously,decreases the working efficiency of drivers after working for 1 hour.
