A new hydraulic draft gear, which has a function of controlling the coupler force, is studied in this paper. The purpose of design of the present device "relief buffer" is to lower the coupler force acting between the failed and the relief train set, which is a very important design factor for the structure of Sinkansen electric-car. The relief buffer assuming the idealized displacement-load characteristics is introduced into the coupling device of the failed train set consisting of 8 light weight new prototype Sinkansen electric-cars and the effect of the relief buffer on the system dynamics is investigated, from which the required specifications are determined on the buffer. Farther, an excitation test is conducted on the prototype buffer composed of a hydraulic cylinder, a servo valve and a feedback controller. The results obtained show that the basic performance of the buffer is satisfactory for the control of coupler force.
