Problems solved by technology

However, the existing energy-absorbing structure has defects such as complex structure, cumbersome production, difficult installation, uncontrollable energy-absorbing method, and poor energy-absorbing effect. The development of a structure and manufacturing process is relatively simple, easy to install, and stable and controllable deformation. A new type of energy-absorbing structure with a larger specific energy absorption is of great significance to those skilled in the art

Embodiment

[0038] a kind of like Figure 3-Figure 6 The guide compound special energy-absorbing structure of the present invention is shown, and the special energy-absorbing structure includes a front baffle 1, a guide rod 2, a thin-walled metal energy-absorbing structure 4 and a rear baffle 5, and the front baffle 1 absorbs energy through the thin-walled metal. The energy structure 4 is fixedly connected with the tailgate 5 as a whole. One end of the guide rod 2 is affixed to the back of the front baffle 1, and the other end of the guide rod 2 passes through the thin-walled metal energy-absorbing structure 4 and is inserted into the through hole 51 provided on the rear baffle 5, and the thin-walled metal absorbs energy. The outer surface of the structure 4 is provided with a groove 41 through which the guide rod 2 passes.

[0039] Such as image 3 , Figure 4 As shown, in the guide composite special energy-absorbing structure of this embodiment, the thin-walled metal energy-absorbing s...

Abstract

The invention discloses a guide combination type special energy absorption structure and application thereon. The structure comprises a front baffle plate (1), a guide rod (2), a thin-wall metal energy absorption structure (4) and a back baffle plate (5); the front baffle plate (1) is fixedly connected with the back baffle plate (5) as a whole through the thin-wall metal energy absorption structure (4); one end of the guide rod (2) is fixedly connected to the front baffle plate (1), and the other end is inserted in the back baffle plate (5) after penetrating through the thin-wall metal energy absorption structure (4); and a groove (41) for penetrating through the guide rod (2) is formed in the outer surface of the thin-wall metal energy absorption structure (4). The special energy absorption structure can be mounted on a front end cross beam of a body chassis structure of a train head, and has such advantages as relatively simple production process, convenience for installation, stable and controllable deformation and high specific energy absorption.

Description

technical field [0001] The invention relates to an energy-absorbing structure and its application, in particular to a special energy-absorbing structure and its application on trains. Background technique [0002] The frequent railway vehicle collision accidents at home and abroad have brought heavy and painful lessons to people. Especially in recent years, with the continuous rise of streetcars, the probability of ground collision has greatly increased. As an important infrastructure of the national economy and a means of mass transportation, railways should always take the protection of the lives and property of passengers and passengers as the starting point for the safety of rail transit operation. Therefore, when train collision accidents cannot be avoided, it is urgent to carry out research on passive safety protection of railway vehicles. [0003] When a railway vehicle has a collision accident, due to the need for passive safety protection during the collision, the...
