It is still facing the long-term challenges to establish the longitudinal vibration and impact model of the train consisting of railway tankers considering fluid-structure interaction in this study field. In order to realize this goal, It designed a railway tank car model whose scaling ratio is 1:5. It studyed the longitudinal impact and vibration characteristics of liquid-solid coupling model for the railway tanker in various filling ratio and various quality of rice based on the method of random decrement technique (RDT) and Morlet Wavelet transform（WT）. Morlet WT is applied to analyze the free longitudinal responses of the railway tank car obtained by random decrement technique (RDT), which can identify resonance frequencies and damper ratio of different condition.
