Abstract

The invention relates to a defect-resistant folding mark type energy absorption box, which belongs to a defect-resistant collision energy absorption box for introducing improved folding mark veins into a thin-wall pipe fitting. The improved folding marks can guide the deformation mode of the thin-wall pipe fitting; high defect-resistant capability is also realized. Compared with an ordinary folding mark type thin-wall pipe, the defect-resistant folding mark type energy absorption box has the obvious characteristics that a diamond concave corner in the folding mark type energy absorption box is improved into a double-trapezoidal concave corner, so that the thin-wall pipe fitting capable of effectively resisting the defect can be formed. By introducing the improved folding mark veins, the requirements of high specific energy absorption rate and low peak load are enabled to be realized; meanwhile, the high defect-resistant capability is realized. In addition, the defect-resistant folding mark type energy absorption box has the advantages that the structure is simple, and the manufacturing cost is low.

Description

technical field

[0001] The invention relates to the structural manufacturing technical field of automobiles, trains, airplanes and other means of transportation. It is designed for the safety structure design of various means of transportation in the event of collision or accident, and in particular relates to an absorbing Kinetic energy crash box device. Background technique

[0002] At present, various types of vehicles, such as automobiles, trains, etc., are more prone to collisions and accidents due to the increasing speed of operation. The violent collisions in such accidents will cause unbearable losses to the lives and properties of the public. Installing specially designed energy-absorbing boxes in the parts of vehicles that are prone to contact is currently the main method for manufacturers to solve collision problems. For various energy absorption and dissipation methods, thin-walled structural metal tubes and various foam sandwich tubes derived from them are very...
