传统上对振动隔离的方法主要包括改变结构的刚度以及在结构外层覆盖阻尼层。本文分别从仿真以及实验上对柔性连接结构以及刚性连接结构的振动传递进行了分析。通过对结构外层覆盖粘弹性材料的振动传递可以发现，外层阻尼能够实现对高频振动的抑制；通过对硬连接结构的内部做空腔处理可以发现，在不改变刚度的条件下，空腔结构能够实现对振动高频的抑制。
The traditional methods of vibration isolation mainly include the change of the stiffness of the structure and the damping of the outer covering of the structure. In this paper, the vibration transmission of the flexible connection structure and the internal cavity containing structure are analyzed from the point of view of simulation and experiment. It can be found that the vibration transfer of the viscoelastic material is covered by the outer layer of the structure, the suppression of high frequency vibration can be suppressed by the outer damping. By analyzing the hard connection structure which with cavity structure in it, under the condition of not changing the stiffness, the cavity structure is able to suppress the high frequency vibration.
