Title

Crashworthiness Design Using to Investigation of Axial Crushing Behaviour of Axisymmetric Tubes

Pages

  108-123

Abstract

 Designing and studying the Energy absorption behaviour is one of theimportant subjects in the industries. The thin-walled metal tube structuresare one of the most widely used types of energy absorbers that havealways been considered by researchers for predicting how to Crushing behaviour and determine the amount of energy absorbed by them. A numerical study of crashworthiness design using to investigation of axial Crushing behaviour of Axisymmetric Tubes is presented in this paper. First, a Finite Element (FE) model for material properties was constructed andvalidated by experimental data. Next, a model for the thin-walled tubeunder Axial loading was adopted. The comparison between the FE resultsas well as the experimental results showed good agreements. The validated FE model was then used to investigate axisymmetric thin-walledtubes with different cross-section and parametric studies of best geometryunder Axial loading. Making a totally 7 different geometries and the collapse behaviour of the absorbent geometries then has been simulated. A comparison of Energy absorption results and maximum Crushing load between the different geometries show that conical tubes with shallowspherical caps are better than others. So, the parametric studies werecarried out to determine the effect of different parameters such as the spherical region radius, semi-apical angle, thickness and foam density onCrushing behaviour of this geometry. The outcomes of the study are new research information which will facilitate the design of axisymmetric thinwalled tubes as energy absorbers in Crushing applications.
