EXPERIMENTAL INVESTIGATION ON VIBRATION TRANSMISSIBILITY OF THE CONICAL SHELL WITH COMPOSITE MATERIAL HONEYCOMB STRUCTURE
The vibration transmissibility of the conical shell with composite material honeycomb structure is investigated by modal experiment and vibration table experiment. Theoretical analysis and experimental results show that the experimental structure has a higher modal damping ratio, and can effectively control the vibration transmissibility in a broad bandwidth, which is the characteristic of vibration isolation system with high damping. The application of composite material reduces the weight of the whole system without sacrificing the dependability of structure.
