Abstract:
Structural analysis of weeder attached frame of robotic paddy weeder using finitie element analysis in terms of Von Misses stress, displacement, and safety factor was conducted in Solid work simulation using finite element analysis at Dr NTR College of Agricultural Engineering, Bapatla. SolidWorks 2018 software was used for the development of 3 D model for weeding frame. AISI 1010 was the material utilized in the construction of the weeder frame for attaching rotsry weeder in this study. Based on the mentioned description of the analysis, the goal of this study was to use SolidWorks 2018 software and the finite element analysis method to examine the weeder frame construction. The minimum value of the safety factor was one of the references used as a gauge of a design's safety. Engineers frequently utilize an object's safety factor as a reference metric when determining how much stress it can withstand. This study's results include Von Mises stress, displacement, and safety factor for determining the material's capacity to sustain dynamic loads and shock loads. When designed load of 1471 N applied on weeder holding frame as per design calculation, lowest value of von Mises stress 0.107 N/m² was observed at the weeder center shaft whereas highest von misses stress of 10.80x10⁷ N/m² was observed at the end of frame attached to main driving shaft which required bearing for bearing dynamic loads. Max deformation of 4.537 mm was observed at the end of frame attached to main driving shaft and minimum was observed at centre shaft of weeder. Due to large deformation at the edge and maximum von Mises stress, bearing support provided for controlling twisting and dynamic loads. The factor of safety was observed as 1.6 which suited for carrying dynamic loads. The weeder support system developed was suitable for carrying static and dynamic loads of weeding system.
