摘　　要：针对目前甘蔗剥叶仿真研究缺少甘蔗茎秆-蔗叶系统仿真模型及甘蔗倒伏机理研究匮乏等问题,根据甘蔗实际的几何参数,采用PRO/E软件建立了甘蔗的三维模型,将其导入ANSYS/LS-DYNA有限元仿真软件。同时,根据测定及反求的材料参数,定义了甘蔗的材料模型,并对模型进行了网格划分,得到甘蔗茎秆-蔗叶有限元仿真模型。结果表明:该模型可用于后续的甘蔗剥叶和倒伏动力学仿真研究。In view of the current lack of research on the mechanism of sugarcane lodging,and the use of dynamic simulation method to study the sugarcane because of the lack of sugarcane stalk-sugarcane leaf system simulation model and other issues. According to the actual geometric parameters of sugarcane,the 3D model of sugarcane was established by PRO/E software,and it was imported into ANSYS/LS-DYNA finite element simulation software. The material model of sugarcane was defined according to the measured and reversed material parameters. Finally,the model is meshed and the model of sugarcane finite element simulation is obtained. The results show that the model can be used for the follow-up kinetics simulation of sugarcane stripping and sugarcane lodging.
