【摘要】 为提高电链锯的锯切效率，对电链锯锯齿的齿形结构参数进行研究，以单位锯切功为电链锯锯切效率的衡量指标，通过对电链锯锯切过程的仿真研究，得出不同结构锯齿的单位锯切功。以电链锯锯齿中的外形前角、侧刃楔角和顶刃楔角等结构参数作为影响因子，采用Box-Benhnken中心组合试验方法设计多因素正交试验，使用Design-expert软件进行数据分析得出最优齿形结构参数组合。研究结果表明，所选取的齿形结构参数对单位锯切功影响程度由大到小顺序依次为外形前角、侧刃楔角、顶刃楔角，并获得最优齿形结构参数组合，外形前角为10.92°、侧刃楔角为45.7°、顶刃楔角为45.41°。更多还原

【Abstract】 In order to improve the cutting efficiency of the electric chain saw, the tooth structure parameters of the saw teeth of the electric chain saw were studied, and the unit cutting power was used as the measurement index of the cutting efficiency of the electric chain saw, through simulation research on the cutting process of the electric chain saw, the unit cutting power of different structure sawteeth was obtained. Using the structural parameters of the external front angle, side edge wedge angle, and top edge wedge angle in the sawtooth of the electric chain saw as influencing factors, a Box-Benhnken center combination test method was used to design a multi factor orthogonal experiment, and the optimal combination of tooth shape structural parameters was obtained through data analysis using Design-expert software. The research results indicated that the selected tooth shape structural parameters had the following order of influence on the unit sawing power, from large to small: external front angle, side edge wedge angle, and top edge wedge angle. The optimal combination of tooth shape structural parameters was obtained, with external front angle of 10.92°, side edge wedge angle of 45.7°, and top edge wedge angle of 45.41°.更多还原
