| Abstract: | The factorial experiments of the parameters of lengthwise edge curve and tiller face height of rotary blade are completed, which aim at obtaining the law of the effect on energy consumption of cultivation Quadratic regression rotation design is applied in arranging and carrying out the plan of experiments After an analysis of variances, a regression equation is developed The proof experiments are done and the predicted value is proved by the result of them Effect of two factors on the energy consumption is analyzed based on the regression equation, and contour lines of energy consumption are drawn The paper presents references for the design of rotary blades |
