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 %
