This paper presents an investigation on a new type of rubber damper , that is , a rubber damper with honeycomb structure . the honeycomb structure will enhance the energy dissipation of a rubber damper and as a result increase the damping of the damper . the performances of honeycomb dampers are experimentally tested by a test rig . the results show that the diameter and the density of holes of the honeycomb structure are important parameters in the design of the damper . for a damper of given size , there are optimum values of both parameters with which the damper provides highest damping . additionally the honeycomb structure does not change the correlation of damping to frequency . a practical honeycomb damper is designe d and applied to inlet pipe of a screw compressor in a petroleum factory for vibration reduction . the vibration of the pipe is obviously suppressed by the damper , at least 25 % 本文采用理论分析和实验相结合的方法，研究了蜂窝孔这种结构因素对橡胶阻尼材料阻尼性能的影响。在自行设计、制作的悬臂式阻尼测试实验装置上，对蜂窝式橡胶阻尼器的阻尼性能进行了大量的实验测试，初步找出了蜂窝孔孔径、孔数以及预压缩量等因素与阻尼器阻尼性能的关系。本文利用实验研究的结论，设计了一种专用的蜂窝式橡胶阻尼器，并应用于某厂螺杆压缩机进口管道的减振，取得了明显的减振效果。
The experimental results further demonstrate that the combination of incompatibility polydimethylsiloxane and polyacrylate by co - vulcanization improves the both compatibility and broadens the low temperature and high temperature functional region . while in sin , to improve microphase structures and damping properties , the design to increase compatibility between two compositions and modulate crosslinking density as well as relative reaction rate of two compositions , is also effective 以上实验结果表明，在复合橡胶阻尼材料中将聚硅氧烷与聚丙烯酸酯通过共混硫化相结合，改进了二者的相容性，拓宽了其阻尼功能区的低温和高温温域；而在sin中通过改善组四川大学博士学位论文分间相容性，调节交联密度控制其微相结构和两种组分相对反应速度的快慢，进而控制材料阻尼性能的设计是行之有效的。
For the purpose of determining the basic problems such as the computed field and the mesh sizes in the finite element method , the paper first deals with the problems of a semi - infinite soil domain with radiation damping and material damping through the transient response of a single pile , which are used in the finite element method 本文首先利用单桩的瞬态响应来考察有限元计算中处理半无限土体的辐射阻尼和材料阻尼问题，以便确定有限元计算区域大小，网格尺寸等基本问题。
