    摘要:

    采用ANSYS/LS-DYNA顯式動力學仿真軟件,，建立甘蔗—切割器系統(tǒng)的動力學仿真模型，且進行了甘蔗切割物理試驗驗證,。利用四因子二次通用旋轉(zhuǎn)組合設計方法和甘蔗—切割器系統(tǒng)仿真模型進行一刀切斷甘蔗的仿真試驗,，建立影響因素與切割力和剪應力的數(shù)學模型，研究了切割力和剪應力各影響因素及其交互作用的影響規(guī)律,，且對影響因素進行優(yōu)化,，獲得了一刀切斷甘蔗時可靠性為95%的最佳切割力總區(qū)間。結(jié)果表明,，刀片刃角為17.5°,，切割角為27.73°，刀盤傾角為28°,，切割速度為16m/s時,，可靠性為95%的最佳切割力范圍為235.82~297.98N。

    Abstract:

    By using explicit dynamic simulation software ANSYS/LS-DYNA, the sugarcane-cutter system dynamics simulation model was established. The precision of the simulation model was verified by physical experiment. By using four-factor of second order general rotation composite design and the sugarcane-cutter system dynamics simulation model, the dynamics simulation of one-blade cutting sugarcane was carried out. The mathematical model of the influencing factors, cutting forces and shear stresses was established. The influence law of the factors and their interaction were analyzed, and the respective optimization of the factors was gained. The optimal cutting force interval with 95% reliability was obtained. The results showed that when knife-edge angle of blade is 17.5°, cutting angle of blade is 27.73°, obliquity of disc cutter is 28° and cutting velocity is 16m/s, the optimal cutting force interval with 95% reliability is from 235.82N to 297.98N.
