Abstract:
• In the agriculture field, a type of equipment to spray chemicals on orchards consists essentially of a vertical structure, with fans and spray nozzles attached, assembled on a vehicle that travels beside the plants. In a simple construction the vertical structure is attached directly behind the agricultural tractor. In a more complex construction, the vertical structure is attached on a trailer, with or without suspension. In some situations, the vertical structure lateral oscillations could affect negatively the results of the treatment. Thus, is important to recognize and even control these lateral oscillations. This dissertation proposes mathematical models for the roll movement of a tower sprayer, and analyzes its responses trough different parameters and excitations. Also analyzes a real case using an orchard sprayer’s parameters to propose a tower suspension to minimize lateral oscillations and accelerations on the structures. The models are based on the inverted pendulum model and can be used for simple orchard sprayer assembled directly on tractors, as well as for that ones assembled on trailers, with or without suspension. The governing equations of the models are deduced by Newton - Euler equations and also by Lagrange’s equations and Hamilton’s principle. The numerical simulations of models ware implemented using the Simulink® module of Matlab® software.
