摘  要：
针对3WPJ-500D喷杆式喷雾机在生产实践中出现的操控稳定性差问题,从喷雾杆式喷雾机在田间作业时药箱内药液晃动产生的附加作用力入手探索,研制了专用的三向力传感器。通过田间试验测量3WPJ-5 0 0 D喷杆式喷雾机在3种行驶速度和6种加液量情况下的药箱药液晃动三向力。药箱药液晃动三向力是一种交变载荷,总体上随加液量和行驶速度的增加而增大。其中,x方向力的峰值为2 025N,出现在400L加液量、4.78 km/h速度工况下;y方向力和z方向力的峰值分别为1 8 1 7 N和5 9 6 N,均出现在5 0 0 L加液量、4.7 8 km/h速度工况下。经计算,喷雾机500L加液量、4.78km/h速度行驶时的药箱药液晃三向力的合力最大值达到2 155 N。试验结果表明:相同工况下同时获得的药箱药液晃动三向力数据的峰值出现的时刻并不一致,但主要的波峰和波谷在相位上接近。该研究可为进一步研究药箱药液晃动力对喷雾机运动的影响以及新型喷雾机的设计提供依据。

摘  要：
To explore the poor handling stability problems of 3WPJ- 500 D boom sprayer that reflects in reproduction practice,this paper conduct the exploratory research about the additional force produced by liquid sloshing in a moving sprayer's tank. In this paper a triaxial forces sensor for measuring liquid- sloshing three- axis force had been developed. Liquid- sloshing three- axis forces are measured in three gears of velocity,six levels of liquid volume of 3WPJ-500 D boom sprayer,got the conclusion that the liquid- sloshing three- axis force is a kind of alternating load and it tend to increase with the rise of velocity and liquid volume. The peak value of x- axis force was 2025 N which appeared in the condition of 400 L liquid load and 4. 78 km / h running speed. The peak values of y- axis force and y- axis force were1817 N and- 596 N,respectively. They all happened in the condition of 500 L liquid load and 4. 78 km / h running speed. The resultant force of liquid- sloshing three- axis forces in full load and 4. 78 km / h speed had been calculated.The maximum value of the resultant force can reach 2155 N. The peak values of liquid- sloshing three- axis forces which measured in the same condition at the same time didn't appear in same temporal points,but their main peaks and valleys had similar phase positions. This research provides basis for the further study of the kinematic and dynamic theories of boom sprayer and offers payload data for the development of innovative boom sprayer.
