Abstract

Technologies and computer programs available today provide us with design programs and analytical techniques for solving complex problems in the different engineering disciplines. These technologies and programs have also found their significance in agricultural research. Computer-aided mathematical modelling was used for carrying out the design optimization of a straight subsoiler. At the initial stage, the static structural analysis under static loading conditions was performed. Details on the material and dimensions for the subsoiler were acquired from the manufacturer at the regional level. The existing subsoiler was then optimized for shank thickness, curve length, and shank width. Optimization was carried out for the objectives seeking minimum solid mass and maximum safety factor. The optimized design obtained was remodeled, and its static analysis performed. Results of the stresses, deformation, and safety factor before and after optimization were compared, and the conclusions drawn. The static structural analysis revealed that before optimization, the subsoiler mass was 24.54 kg, and the volume was 3117701.77 mm3. The maximum total deformation was 4.959 mm, maximum equivalent stress was 270.09 MPa, and the maximum principal stress was 295.06 MPa.  The minimum value for the safety factor was 1.296. Parametric correlation of the input and output parameters showed that the relationship among two input parameters viz. shank thickness, shank width, and output parameters was strong. These input parameters were used for response surface generation and design optimization. Optimization reduced both the subsoiler mass and volume by 14.86 %. The maximum equivalent stress and maximum principal stress reduced by 4.10% and 5.39%, respectively, while the total deformation, minimum safety factor, and maximum working life increased by 7.15%, 4.28%, and 14.26%, respectively.
