Car Body Structure

This article emphasizes on finite element modeling and simulation of train car body structure in order to ensure a crashworthy structure. Crashworthiness is a principal parameter to be considered to be taken into account in case of design of train car body structure. The present paper deals with the development of virtual prototype with energy absorption capabilities. The train car body structure with trapezoidal core has been modeled using SOLIDWORKS® software. The entire crash simulation in the present study was done by using LS-Dyna® Explicit finite element software. The crash analysis of train car body over a rigid concrete wall was numerically simulated at three different speeds viz. 60 km/hr, 90 km/hr, 120 km/hr. In every crash analysis, the stress plot and history of deformation from the developed virtual prototype. The simulation of the rail vehicle collision presented in this article is based upon the standard specified in crashworthy section of Technical Standards of interoperability. The dynamic numerical simulation of two train car bodies with equal velocities has also performed using LS-Dyna®.

For traditional ordinary concrete wall column prone to thermal bridges, posted outside the insulation board short life than the life of the building，in the glazed hollow bead of recycled concrete foundation with good thermal conductivity test and compressive strength of the proposed ,use glazed hollow bead of recycled concrete exterior wall column instead of the traditional ordinary concrete wall column ,and using the finite element software ANSYS simulation analysis the uniaxial compression of glazed hollow bead of recycled concrete short columns and ordinary concrete short columns. Comparative analysis showed the same intensity level glazed hollow bead of recycled concrete ultimate compressive bearing capacity of an analog value the same as ordinary concrete short columns. To validate the ANSYS simulation of concrete short columns under uniaxial compression condition .

Analysis Technique

Abstract Design Sensitivity Analysis (DSA) is a widely used technique in many areas of finite element analysis, but one that hasn’t yet become available for industrial problems in crashworthiness and automotive safety. In the following effort, an implementation of DSA in the automotive safety simulation program, Radioss, is described. Radioss is a non-linear structures program using an explicit time integration method. A full set of DSA equations are developed and integrated into Radioss so that the design sensitivities can be computed directly and accurately as a result of a single crashworthiness simulation. Some validation results are included. The resulting methodology promises to be an extremely useful tool for engineers involved in the design of safety and crashworthiness of automobiles.

Virtual Velocity

The dynamic explicit finite element software DYNAFORM was used to simulate the real and equivalent drawbead model. Analyzed the influence of the blank hold force (BHF) and virtual velocity on blank’s deformation behavior after passing through drawbead, compared the results of the FE simulation. The simulation results were confirmed by experiments. The study shows that the equivalent drawbead model can’t simulate the blank’s behavior precisely when it passing the real drawbeads, the effect of BHF on real drawbead model is larger than equal drawbead model; the proper range of virtual velocity was obtained at the same time.
