The invention discloses a controllable-deformation railway-vehicle front-end anti-crawling energy absorption structure. The controllable-deformation railway-vehicle front-end anti-crawling energy absorption structure is characterized by comprising an anti-crawler component, a crushing box structure, edge beam components on the two sides and an end beam; the crushing box structure is fixed betweenthe anti-crawler component and the end beam, and the edge beam components on the two sides are connected with the anti-crawler component and the end beam to form a box-shape frame. The controllable-deformation railway-vehicle front-end anti-crawling energy absorption structure has the advantages that the front-end anti-crawling energy absorption structure can move according to the preset process through calculation and experimental verification, is sequentially deformed, meets the requirement capable of absorbing 1.22 MJ energy, and is integrated with the front-end anti-crawler structure, andthe passive safety protection performance of a train is greatly improved; meanwhile, the crushing box structure, namely, an energy absorption deformation area structure is simple in manufacturing technology, and the vehicle manufacturing cost is saved.
