摘要
使用Matlab/Simulink软件,建立了树叶在风中振动的仿真模型,得到了单片树叶无序运动的位移、速度,通过对多片树叶的无序振动取统计平均,发现树叶在风中做小幅度的振动,其机械能是近似守恒的。
Using Matlab/Simulink software,the simulation model of leaf vibration in the wind is established,and the displacement,velocity of the disordered motion of the leaf are obtained.By taking the statistical average of the disordered vibration of multiple leaves,we find that the leaves take a small amplitude of vibration,and the mechanical energy is approximately conserved.
