The invention discloses a fixing device for buffer material vibration transmission test. In order to overcome the shortages that static pressure application on a fixing device of the package buffer material vibration transmission characteristic test is lack of operability, and static pressure adjustment is inconvenient, the invention design a fixing device. The fixing device is provided with a device, which can adjust the static pressure of buffer materials, and a sensor, which can realtime measure the static pressure. A sample to be tested and a quality block are disposed on a vibration platform by using the fixing device, the upper sample is loaded and fixed according to a given static pressure, and the vibration test system is immediately started right after the pressure sensor is dismounted to perform a material vibration transmission characteristic test. The fixing device for buffer material vibration transmission test is suitable for being used in buffer package material production entrepreneurs, transportation package design institutes, and labs of teaching and research institutes.
