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。
