摘　　要：利用ANSYS/LS-DYNA软件对甘蔗深耕犁的翻土过程进行动力学模拟仿真。根据犁体曲面生成原理,使用参数法建立犁体曲面的数学模型,并利用Pro/E软件建立犁体曲面的虚拟模型,在此基础上进行动力仿真分析,得到犁体曲面在翻土过程中犁耕阻力的变化曲线图。ANSYS/LS-DYNA software is used to carry out the turning dynamics simulation of sugarcane deep tilling plough. According to the plow surface generation principle, the mathematical model of plow surface is established by using the parameters, then by Pro/E software to establish the virtual plow surface model, based on which the dynamic simulation analysis was conducted, and the resistance curve of surface in the process of plow turning was found.
