摘要：本文根据某型光电吊舱无角位移减振的需求，利用分级减振的设想，设计了一组内外框架减振器，计算了减振器刚度、阻尼系数范围，并对减振器进行了合理的布局，建立了减振系统的Solidworks三维模型，在ADAMS中进行了振动仿真分析，得出了单方向输入时系统的幅频响应曲线，并对系统参数进行了优化，确定了减振器的刚度、阻尼系数的最优值，结果表明，该系统实现了三向相等刚度，解除了系统三个方向的线振动耦合，保证了荷载基准与底座基准振动状态下无相对角位移。

Abstract: According to the demand of non-angular isolation for a certain of optical pod, the new type of inner and outer shock absorbers which could limit the angular displacement between the base and load were designed. And the stiffness and damping of the absorbers were calculated, the vibration isolation system which the two absorbers were reasonably placed was also be designed. The three-dimensional models of the absorbers and the system were built by using the software of SOLIDWORKS, then the simulation of the system was done by using ADAMS/vibration, the frequency response curves were obtained,and the optimal stiffness and damping were also obtained by the simulation optimization, The results show that the new system not only has the same stiffness in three directions, but also can remove the line vibration coupling and the relative angular displacement between the load and base.
