Optimization of structural elements of subsoiler by response surface method

The aim of the research presented in the paper is to reduce the mass of the structural elements of the subsoiler using the response surface optimization method. Two structural elements are optimized tine and structural support. The CAD model of the subsoiler was created in SolidWorks, a CAD system for parametric modeling using features. For the purpose of optimizing structural elements, soil load calculations were made using the Matlab software package. The geometric parameters of the structural elements, which represent the input parameters, were optimized. Output parameters (responses) consist of mass, maximum equivalent stress according to von-Mises and deformations. After the optimization, the control calculation of the optimized structural elements was made again with regard to s tresses and deformations. Through the control calculation, the stresses and deformations of the optimized structural elements meet the permissible values.
