A corrugated composite energy-absorbing device and a rail vehicle with the same

Abstract

The invention discloses a corrugated composite energy absorbing device and a rail vehicle with same. The corrugated composite energy absorbing device comprises an anti-creeping toothed plate, an energy absorbing component and a rear baffle; the back surface of the anti-creeping toothed plate is connected with a guide rod; the energy absorbing component comprises a corrugated plastic deformation energy absorbing component and an enhanced energy absorbing component; the corrugated plastic deformation energy absorbing component is a column body with a central through hole and is surrounded by a plurality of alternately arranged guide plastic deformation pipes and corrugated plates; the enhanced energy absorbing component is arranged in the central through hole in a sleeving manner; and a freeend of the guide rod is inserted in a guide through hole formed in the rear baffle after penetrating through the guide plastic deformation pipes to be fixedly connected so that the two ends of the energy absorbing component are correspondingly in contact with the anti-creeping toothed plate and the rear baffle. The rail vehicle with the corrugated composite energy absorbing device can stably runin an orderly and controllable manner according to a preset corrugated path; compared with a traditional energy absorbing structure, the corrugated composite energy absorbing device has the advantagesthat more stable load-displacement curve is obtained, over-high initial peak force does not exist, larger instant load generated in the impact energy absorbing process can be effectively avoided, andinjuries to passengers and damages to a vehicle body are further reduced.

Description

technical field [0001] The invention relates to the technical field of passive safety protection for rail vehicles, in particular to a corrugated composite energy-absorbing device and a rail vehicle with the device. Background technique [0002] Rail transit is the lifeblood of the national economy. At the same time, my country's high-speed rail network is gradually improving, and the huge economic and social benefits it has gained have attracted worldwide attention. This has set an excellent example for the export of rail equipment, rail systems and other products. [0003] Under the promotion of this development trend, in order to better meet the needs of human beings, the safety of rail train operation should attract enough attention. Once the train collides, its huge kinetic energy will lead to multi-vehicle coupling impact. After a collision occurs, the connected cars will contact the front car one after another in a contact collision. In particular, collisions when h...
