【摘要】 本文选择影响锯链锯木过程的四个主要锯木参数,即;切削速度、同名齿进给量、锯口长度和进锯角为试验因素,以切削力、锯木功率、锯木生产率和单位锯切比功为试验指标(以下称锯切指标),在锯木试验台上进行正交试验,通过对试验结果进行极差分析,得出适合于节距10.26 mm锯链不同输出功率的最佳切削工况,这对动力链锯的设计、改进和使用具有一定的指导作用。更多还原

【Abstract】 The four main cutting parameters such as; cutting speed, thickness of the cut pieces of wood, cuting length and angles, which may affect the cutting procedure were chosen as the test factors. And the cutting force, cutting power, cutting productivity and the unit cutting power were considered as test indexes. The orthogonal test was conducted on the test table. The optimal cutting condition for the chain saw with the pith of 10.26mm under different output power has been obtained. The results have significance for design, improvement and usage of the power chain saw.更多还原
