Based on the designed cane straw cutting blade,a cutting power consumption model is created.The minimum cutting power consumption is taken as the objective function and optimized.The optimal sliding angle is 40°.Orthogonal experiments were carried out on the three main influencing factors of cutting power consumption.The results showed as follows:Firstly,when the water content of straw increased,the cutting power consumption increased with the increase of water content.Secondly,when the amount of single cutting increased,the cutting power consumption also increased.Thirdly,in the same cutting condition,the serrated blade of 40° sliding angle had the lowest cutting power consumption and the highest cutting efficiency.The results of the two statistical methods showed that the blade type had the most significant effect on the cutting power consumption,then the water content of straw,and finally the single cutting amount.The optimum combination was that the water content of straw was about 20%and the single cutting amount was 6 kg,the blade type was serrated blade of 40° sliding angle.
