The invention discloses a train collision energy absorption structure, and relates to the technical field of train energy absorption structures, the train collision energy absorption structure comprises an energy absorption body, a first cavity and a second cavity are arranged in the energy absorption body from front to back, damping fluid is arranged in the first cavity, a collision rod is mounted at the front end of the first cavity, and the front end of the collision rod extends out of the first cavity; the rear end of the collision rod is connected with a first sliding plate, and the rear end of the first cavity is provided with a damping channel communicated with the second cavity. The cross section area of the second cavity is larger than that of the first cavity, and an elastic element is installed between the rear side of a second sliding plate installed in the second cavity in a sliding mode and the rear side wall of the second cavity. Furthermore, the damping fluid is preferably magnetic fluid, the viscosity of the magnetic fluid can be quickly regulated and controlled through an external magnetic field, and the overflowing area of the damping channel can be regulated by arranging a regulating device. According to the energy absorption structure, the effective crushing stroke of the energy absorption structure can be greatly increased, and the impact force can be quickly regulated and controlled by changing the overflowing area of the damping channel or regulating and controlling the viscosity of the magnetic fluid.

    本发明公开一种列车碰撞吸能结构,涉及列车吸能结构技术领域,包括吸能本体,其内由前至后设置有第一腔体和第二腔体,第一腔体内设置有阻尼流体,第一腔体的前端安装有碰撞杆,碰撞杆的前端伸出第一腔体,碰撞杆的后端连接有第一滑板,第一腔体的后端设置有阻尼通道与第二腔体连通;第二腔体的横截面积大于第一腔体的横截面积,第二腔体内滑动安装的第二滑板的后侧与第二腔体的后侧壁之间安装有弹性元件。进一步地,阻尼流体优选为磁流体,通过外加磁场可快速调控磁流体粘度,而且设置有调节装置能够调节阻尼通道的过流面积。本发明能够大幅增加吸能结构的有效压溃行程,且可通过改变阻尼通道的过流面积或调控磁流体粘度来实现撞击力的快速调控。
