Abstract
Design and experiment of electro hydraulic active suspension for controlling the rolling motion of spray boom
Highlights
With the continuous growth of the world population, agricultural productivity will continue to increase
Taking the control system of active suspension as the research object, a high-performance control system hardware circuit and human-computer interaction interface based on DSP28335 chip are designed
The main conclusions are as follows: 1) In order to prevent the wrong response of the control system caused by the high frequency component due to uneven crop canopy or rough ground
Summary
With the continuous growth of the world population, agricultural productivity will continue to increase. It is estimated that agricultural productivity will increase by 60% by 2050[1]. The boom sprayers are widely used in crop protection on the fields against diseases, weeds, pathogens, and others[2,3]. The width of the mainstream boom sprayer in China is about 10-24 m, unwanted boom motions typically occur when sprayer tires go over uneven terrain field surfaces[4,5]. Mainly vertically rolling has a dramatic effect on the spray distribution pattern[6,7]. It is pointed out that the efficiency of chemical pesticides is highly correlated with the uniformity of the spray distribution pattern[8]
