Vibration transmissibility formula under random vibration was derived theoretically. Vibration transmissibility properties of honeycomb paperboard under random vibration of different acceleration, frequency and stress were tested; the vibration transmissibility curves and peak frequencies were obtained. The result showed that the vibration transmissibility from different random vibration tests is much the same and very close to the result of sine sweep test. It was concluded that using random vibration test to analyze the vibration transmissibility of honeycomb paperboard is feasible.
