Abstract: The article presents a method for developing parameters and operating modes of a gear spring harrow using a three-factor experiment of the Bk plan. The regression equation of the machine’s working process, its optimal value (specific traction resistance 432.8 N, angle of inclination of the teeth of the harrow 61.9 degrees, angle of grinding of the tooth 20.98 degrees) and operating parameters (operating speed of the unit 11.7 km / h). The dependences of the response function (specific traction resistance of the tooth-spring harrow) on its parameters and operating modes are represented by mini-max. Hypersurface plots. To determine the nature of the response surface in canonical form near the optimum, two-dimensional sections of its surface are constructed with a family of conjugated isolines, with the help of which the interaction of factors is studied.
Keywords: Experimental Design, Regression Equation, Response Function, Factors, Analysis, Hypersurfaces, Two-Dimensional Sections.
