摘　　要：在农业药物喷雾过程中,由于喷雾器在水平和垂直方向不必要的频繁运动,造成喷雾的不足或过量,产生农药的浪费、残留和环境污染等问题。为此,设计一种按照不同地形、不同振动程度进行实时调节的喷雾系统,并进行仿真测试。首先通过ADAMS和Mat Lab建模,然后使用五轮仪进行路谱数据采集并结合Lab VIEW进行联合仿真,与此同时进行1Hz0.5g、2Hz0.5g、1Hz1g这3种正弦激励的试验。数据显示:当振幅由0.5g增至1g时,加速度的增幅将近50%;当频率从1Hz增至2Hz时,加速度的增幅则超过了50%。在速度为5km/h和8km/h的两种情况下进行实地与仿真测试,仿真的结果与路面激励下喷雾器喷杆的实际振动情况基本相符。In the process of drug spraying in agriculture currently , due to the nebulizer frequent and unnecessary move-ment in the horizontal and vertical directions , it resulted in spraying insufficiently or excessively , caused many issues such as waste , residue , environmental pollution and so on .Therefore we designed a spray system that carried out real-time adjustment and made simulation tests which according to different topography and vary degrees of vibration .ADAMS and MATLAB were applied to model firstly , and then the data of road spectral were collected through the fifth wheel method and made the co-simulation with LabVIEW , meanwhile we conducted three kinds of sinusoidal excitation experi-ments which were 1Hz0.5g, 2Hz0.5g,1Hz1g.With data displayed that , when the amplitude increased from 0.5g to 1g, the growth in acceleration was nearly 50%,when the frequency was increased from 1Hz to 2Hz, the growth in accelera-tion was more than 50%.The test of reality and simulation were both carried out under the conditions of 5 km /h and 8 km /h , the simulation results conformed to the actual situation nearly .
