中文摘要：

利用弹性理论，采用双梁模型对甘蔗茎秆材料的切割进行了理论建模，并得出了蔗材切割力的理论计算公式。以单向复合材料为甘蔗茎秆的材料模型，分析了影响切割力的因素，建立了甘蔗材料单位切割力的经验公式。通过对甘蔗切割力试验数据的分析，得出本文试验条件下的甘蔗茎秆切割力经验公式，并通过试验对该经验公式进行了验证。

英文摘要：

By using elastic theory and double beam model, the theoretical cutting force formula in cutting sugarcane stalk material was made in this paper. Based on the theoretical formula and taking single direction composite material as the model of sugarcane stalk material, the experimental unit cutting force formula for sugarcane stalk was made through analyzing its influencing factors. By analyzing the test data of cutting force, the experimental unit cutting force formula for sugarcane stalk was developed under the conditions of this paper. The experimental formula for sugarcane stalk was verified by cutting force test.
