为究明振动对免耕播种机排种性能的影响，采用Pulse LAN－XI 振动测试系统，对2 BM－5型气吸式免耕播种机在莜麦茬地作业状态下排种器的振动特性进行了测试；用 MatLab对振动信号进行时域和频域分析，得到播种机在作业状态下田间振动信号的时域图及频域图。试验结果表明：在免耕播种机作业状态下，随着速度的提高，振动主频率对应的最大幅值有所提高；排种器的振动主频率主要集中在0～10Hz 和40～60Hz；在莜麦茬地播种，2 BM－5型气吸式免耕播种机作业速度为4 km／h时振动较弱。

To clear seeding performance of no tillage planter,this paper pulse LAN-XI vibration test system is adopt, the vibration characteristics of 2 BM-5 type of suction and no tillage planter in the stubble land of naked oats state discharge device were tested, time domain and frequency domain analysis of vibration signals are obtained by Matlab process.Test results show that in the no tillage planter state, with increasing of velocity, vibration frequency corresponding maximum amplitude increased; the metering device vibration frequency is mainly concentrated in the 0-10 Hz and 40-60 Hz; so-wing in the stubble land of naked oats, the vibration is weak when working velocity is 4km/h for the no tillage planter.
