Abstract: The computer aided engineering analysis and design optimization of rotary tillage tool on the basis of finite element method and simulation method is done by using CAD-software for the structural analysis. The different tillage tool parts of rotary tillage tools are geometrically constructed as a solid model. The actual field performance rating parameters along with boundary conditions are set in the software for 35 hp and 45 hp tractor. The estimated forces acting on soil-tool interface are fed into software as a loading condition. The resultant effects of loading condition on tillage blade and whole rotavator assembly were obtained from stress distribution and deformations plots. The proposed working results in identifying sufficient tolerance in changing the dimensions of rotavator frame sections and side gear box for removing the excess weight in a solid section and also to raise the weight of blade for a reliable strength. The present working model with tillage blade is analysed to new design constraints with change of its geometry for the maximum weed removal efficiency by presenting its practical results from the field performance.Keywords: rotary tillage tool, simulation, FEM, design analysis, stress, deformation, rotavatorDOI: 10.3965/j.issn.1934-6344.2011.03.001-006Citation: Gopal U Shinde, Shyam R Kajale.
