摘　　要：为探明免耕播种机在玉米留茬地作业时排种装置振动对排种特性的影响,采用六通道pulse LAN-XI振动测试系统及加速度传感器,分别测试免耕播种机在玉米免耕地不同速度作业状态下排种器的振动特性,并对其进行频域分析,得到振动信号的频谱图。分析结果表明：在免耕播种机作业状态下,排种器的振动主频主要集中在0~10Hz与40~55Hz;随着速度的提高,振动的主频率有所提高,在速度为3.6km/h时振动的主频率是最小的,是适合播种机播种的适宜速度。To study out in the corn stubble tillage planter to the job when the impact of vibration on seed metering device characteristics, we use six-channel pulse LAN-XI vibration test systems and acceleration sensors were tested in no-till corn planter different tillage vibration＇s job status row planted speeds, and its frequency domain analysis, frequency spectrum of vibration signal. The results showed that ： In no-till planter job status, seeder vibration frequency is mainly concentrated in the 0 - 10Hz and 40 - 55Hz, with increasing speed, the main frequency of vibration increased at a speed of 3.6km/h of the main frequency of vibration is the smallest, and is suitable planter suitable speed.
