COMPUTER AIDED DESIGN AND ANALYSIS OF ROTARY TILLAGE TOOL COMPONENT FOR FAILURE

This paper presents stress analysis of rotavator blade for different thickness and different materials. We have selected L-shaped blade for the study because L shape is usually superior to others in heavy trash. They are better for killing weeds. Rotavators work in the very difficult conditions, so they bear heavy dynamic loads. Therefore, proper design of these equipment is necessary to increase their working life time and reduce the farming costs. For the study we have selected A 15 HP Mahindra Yuvraj 215 tractor and Shaktiman SRT 2.5 mini rotavator. We calculated Forces acting on each blade for different thickness as well as different materials. After modeling of blade, we applied boundary and loading conditions on the models. Finally, models were analysed with analysis software. Results of this research can help the designers of rotavator blade to make similar works in their designs and increase the working life of blad
