Abstract

Abstract

In order to improve the safety-impacting speed of freight organized into groups' spot and manipulating vehicle efficiency, a new type of hydro-pneumatic buffer for railway vehicle was developed, its basic structure and principle were summarized, a lognitudinal dynamics calculating model of train with the buffers was established, the dynamic characteristic of the buffer was analyzed by numerical simulation method. The calculating result shows that the buffer capability may reach 160 kJ, and its absorptivity may exceed 90% in the condition that the biggest impedance force of the buffer is no more than 2200 kN as manipulating vehicle, the impacting speed of manipulating vehicle is increased, the lognitudinal impulsion and libration between vehicles are decreased and dissipated, the hydro-pneumatic buffer may be adapted to the request of heavy loading and speed increasing train.
