摘　　要：本实验采用abaqus有限元分析软件,对木材高速撞击时的动态特性进行仿真分析。推导了碰撞理论的基本方程;根据实验内容和实际要求,选取实验试件,确定了其尺寸和物理性能参数;进行仿真实验,对撞击杆进行规格和物理性能参数的设定,约束其边界条件和加载速度;通过后处理获得了各节点的特性曲线。分析特性曲线获得了木材在高速撞击下的应力、位移、能量变化关系,对今后的木材高应变率下的动态特性研究提供了参考依据。The experiment uses abaqus to simulate and analyse dynamic characteristics of wood under the high-velocity projectile impact.The paper deduces the basic equation of collision theory.The experiment chooses suitable specimen and confirms their size and physical performance parameter.During simulation experiment,the specifications and physical performance parameter of trip rod were set,and the boundary condition and loading speed were constrained.Finally,the characteristic curve of each node was obtained.The experiment obtained stress,displacement and energy relationship of wood under the high-velocity projectile impact.It provides reference basis for studying dynamic characteristic of wood under the high-velocity projectile impact.
