Design and Experimental Study of a Crawler-type Precision Pesticide Applicator Based on Dem
Year: 2025
Type: article
Abstract: This study is based on the discrete element method to design a tracked precision solid particle pesticide applicator and establish a coupling model between the pesticide application device and particle swarm EDEM. Simulation shows that particle characteristics significantly affect the uniformity of pesticide application. The coefficients of variation for particles 1, 2, and 3 are 4.25%, 4.63%, and 5.57%, respectively, with relative deviations of 8.51%, 9.28%, and 11.33%. After response surface testing optimization, the measured coefficient of variation of the prototype was 8.25% and the relative deviation was 18.07%, both of which met industry standards.
