The Analysis and Experimental Study of Sawing Performance Parameters of Caragana korshinskii Stems
摘要
Abstract
To investigate the mechanical characteristics of Caragana korshinskii stem sawing and determine the optimal sawing parameters for supporting the subsequent optimization and improvement of shearing equipment,a self-designed branch sawing test platform was used in this study.Single-factor experiments were conducted to examine the effects of stem diameter,cutting speed,feeding speed,cutting angle,and saw blade tooth count on the peak cutting force and cut-ting power of the branches.Building upon the results of the single-factor experiments,a Box-Behnken central composite experimental design was employed.Selecting cutting speed,feeding speed,cutting angle,and saw blade tooth count as experimental factors,a multi factor experiment was carried out with peak cutting force and cutting power of branches as target values,and a regression model was established.The experimental results showed that the peak cutting force in-creased with the increase of stem diameter,while it exhibited an initial increase followed by a decrease with the increase of cutting speed,feeding speed,cutting angle,and saw blade tooth count.Similarly,the cutting power increased with the increase of stem diameter,but initially decreased and then increased with the increase of cutting speed,feeding speed,cutting angle,and saw blade tooth count.Multi-objective optimization analysis of the regression model yielded the optimal combination of parameters:cutting speed of 45.7 m/s,feeding speed of 0.32 m/s,cutting angle of 8.3°,and tooth count of 104.Under these conditions,the peak cutting force was 7.02 N and the cutting power was 181.57 W.The deviation between the predicted value and the actual value of the peak cutting force and cutting power was 1.9％and 2.2％,respectively.The results of this experiment provide valuable reference for the design of efficient and low-energy consumption Caragana korshinskii shearing equipment.关键词
