Abstract:
A laboratory setup was created, examined, and constructed to assess the effectiveness of a sensor-based weed detection and variable rate herbicide application system in weed recognition and precise herbicide application. The specific dimensions of lab setup were (112.0× 71.0× 71.5 cm3). The lab setup consisted of mechanical system and power transmission system which was integrated with image processing system for weed detection and smart spraying system for chemical application. The mechanical system of lab setup was modelled, analyzed and fabricated using Finite element Analysis (FEA). The mechanical system was geometrically modeled in Creo parametric 5. Chassis and base frame were the key structural mechanical component for support and accommodation of the other components. The designed components were tested for structural strength in Creo simulation 5.0 using Static FEM analysis and validated for the design consideration. Chassis and base frame were loaded with total of 0.8 kN and 1,2 kN normal load. The maximum von mises stress, and strain developed within the chassis and base frame were (44.12 MPa, & 8.89 MPa) and (2.200×10-4 & 3.973×10-5) respectively. The stress and strain induced in chassis, and base frame were within the safe limit of material. Therefore, base frame and chassis frame design were accepted for the design limits and laboratory setup was fabricated. All the other components procured were mounted to lab setup. The computer aided design using creo-parametric software was found suitable to reduce the time required for repetitive design calculation, fabrication, and assembling work during the actual entire fabrication process.
