摘要
文章通过采用ANSYS/LS-DYNA计算软件,建立了三种位置条件下减震沟的数值模型,计算分析了减震沟在不同位置条件下对其减震效应的影响规律。计算表明:当减震沟与保护目标较近时,减震效果较好;当减震沟与保护目标较远时,减震效果较差。
With ANSYS/LS-DYNA software,three kinds of damping ditch models with different location are established.The damping rule when damping ditches are located in different ways is analyzed in this paper.The results show that damping effect is better when damping ditch closes with protected object,vice versa.
