Test method for boom suspension influence on spray distribution. Part II : Validation and use of a spray distribution model

Abstract : In part A of this paper, an experimental study of the influence of boom movements on ground distribution showed that a geometric static model should correctly be used for simulations. Such model was developed in Cemagref (Sinfort et al., 1994). The objective of this second part is to validate the results of this model for several kinds of solicitations in laboratory and field conditions: laboratory validation used a conveyor and a shaking platform to reproduce pure vertical and horizontal movements; field validation was assessed on both concrete and field tracks to analyse combined movements. Then the model was used to define an evaluation method for sprayer boom behaviour at farm level. The concept is to ride the sprayers over a bump, to measure boom movements and to simulate the distributions. The evenness is assessed through the coefficient of variation (CV) and the percentage of area correctly sprayed.
