Design method of split type energy absorption structure

Abstract

According to a design method of a split type energy absorption structure, the energy absorption structure can achieve adjustment of energy absorption and change of buffering force through difference of fiber winding, the number of layers, the wire diameter and the material of a composite material energy absorption pipe. Meanwhile, a protruding cut-off tool is arranged in the composite material energy absorption structure and used for cutting composite material fibers, so that compared with a metal planing energy absorption device, a metal pipe expansion energy absorption device and a metal pipe contraction energy absorption device, variable-force-value energy absorption can be achieved. The material is low in density and light in weight. The energy absorption structure has the advantages of being controllable in energy absorption and convenient in buffering force design.

Description

Technical field [0001] The present invention belongs to the field of rail vehicle manufacturing techniques, in particular, to a design method of a suction structure. Background technique [0002] Passive safety research on railway vehicles, adopting appropriate capsules, improves train campaign, minimizing accidental losses. The so-called train resistance refers to the comprehensive characteristics of the load capacity of the train structure, the formation form, and the ability of the train structure itself absorb the ability to absorb the ability of the train structure. The resistance to the train is not required to have a train structure without damage, but to ask the train at a certain impact speed, the secondary part of the train structure can be deformed in an orderly manner, more absorption. The impact kinetic energy can effectively reduce the impact acceleration, and the vehicle body structure can provide survival to the passengers in the passenger and passengers to reduce...
