| 摘 要： | 橡胶具有多自由度弹性阻尼减振特性,但容易老化而失去弹性,首次提出采用多自由度并联机构作为基体辅以稀土永磁及浮动弹性阻尼系统,组合成多自由度弹性阻尼减振装置,模拟橡胶,较好地解决了多自由度的减振问题。以救护车用担架支架三维隔振装置为例分析其隔振要求,采用三自由度并联机构组合弹性阻尼减振装置,介绍其结构及有关参数的设计方法。它与动态模拟及试验结果一致,说明其分析方法是正确的。可推广到其他要求多维减振的设备上,因此对它研究具有理论意义及普遍意义。

| Abstract: | The combined elastic damping devicesbased on multiple DOF parallel mechanism as well as rare-earth permanent magnet materials and floating elastic damping system are adopt for the first time to solve the problem of multiple DOF vibration reduction. The structure and the parameter design of stretcher frame in ambulance using the kind of devices are presented. Its dynamic simulation values are the same in comparison with the experiment data, and the result shows that it is a correct method. The method may be generalized for other multiple DOF devices. So its study has theoretical and general significance. |
