摘　　要：圆锯片锯切绿篱枝条属于高速侵彻过程,圆锯片受力复杂,圆锯片和枝条之间的相互作用不便观察和分析。ANSYS的LS-DYNA模块为锯切过程提供了研究的途径,可以对圆锯片锯切绿篱枝条的过程进行显示动力学模拟分析。现有的锯切研究对象主要以石材和干木材为主,与圆锯片锯切绿篱枝条相关的模型和研究很少,故模型是在不断探索和验证的过程中建立的。通过对圆锯片锯切枝条模型仿真求解的结果与实际锯切过程和实测数据进行对比,验证了所建模型的合理性与正确性,为以后此类问题的研究奠定了基础。The process of circular saw blades sawing hedge branches belongs to high speed penetration, and the forces on the circular saw blades is complicated, and the interaction of sawtooth and branch is difficult to observe and analyze. The LS- DYNA module of ANSYS offers a way for sawing process, which can display dynamic simulation analysis for the process of circular saw blades sawing hedge branches. The available studies of cutting subjects are mainly focused on stone and wood, and there are little model and research related, so the model of this study is built on the constant exploration and verification. According to making comparisons between simulation result and experiment data, the rationality and correctness of the model is verified, which lays the foundation to the study of related issues.
