The invention belongs to the technical field of rail traffic safety protection, and particularly relates to a cavity-divided type high-speed train buffering energy absorber. A cavity-divided buffering energy absorber for a high-speed train comprises a buffering cavity, a buffering medium is arranged in the buffering cavity, a plurality of cavity dividing plates are arranged in the buffering cavity and divide the buffering cavity into a center cavity and a plurality of outer cavities, an oil pressing piston is arranged in the center cavity, the bottom of the oil pressing piston makes contact with the upper portion of the buffering medium, and the bottom of the oil pressing piston makes contact with the lower portion of the buffering medium. The top of the oil pressing piston extends out of the buffering cavity. A front buffer plate is arranged over the top of the oil pressing piston, and the back of the front buffer plate is fixed to a front compartment coaming. A rear buffer plate is arranged at the bottom of the buffer cavity, and the back of the rear buffer plate is fixed to a rear carriage coaming. According to the buffer device, impact energy is converted into potential energy for deformation of the buffer cavity, the buffer cavity is divided into the multiple cavities, the multiple cavities deform one by one, the purpose of multi-stage energy absorption is achieved, and the passive safety protection capacity of a train is improved.
本发明属于轨道交通安全防护技术领域,具体涉及一种分腔式高速列车缓冲吸能器。一种分腔式高速列车缓冲吸能器,包括缓冲腔体,所述缓冲腔体内设置缓冲介质,缓冲腔体内设置有多个分腔板,分腔板将缓冲腔体分隔为中心腔和多个外腔,中心腔内设置有压油活塞,压油活塞的底部与缓冲介质的上部接触,压油活塞的顶部伸出缓冲腔体。在所述压油活塞顶部的正上方设置有前缓冲板,前缓冲板的背部固定在前车厢围板上;在所述缓冲腔体的底部设置有后缓冲板,后缓冲板的背部固定在后车厢围板上。该种缓冲装置通过将冲击能转化为缓冲腔形变的势能,并将缓冲腔分隔为多个腔体,通过多个腔体逐个发生形变,来达到多级吸能得目的,提高列车被动安全防护能力。
