The invention discloses a small hydraulic buffer impact test method and device, and the method comprises the following steps: first, a small hydraulic buffer is vertically fixedly arranged, a buffer rod is vertically upward, an impact load and the hydraulic buffer are arranged on a same vertical line, and the impact load is arranged on a set height above the hydraulic buffer; the impact load freely falls onto the hydraulic buffer for drop-hammer impact; a plurality of different buffer state images in the buffer process of the hydraulic buffer can be obtained by use of a high-speed camera; and finally, the number of the shot images in the buffer process can be obtained by analytic statistics by use of dichotomy, and the buffer time of the hydraulic buffer can be obtained by dividing the number of the shot images by shooting frame rate of the high-speed camera. Through measuring the buffer time of the small hydraulic buffer for further obtaining the mechanical system actuation time, the buffer property of the hydraulic buffer can be judged, the method is simple, and test results are accurate.
