“…RCAR test regulation impacted at the velocity of 4.44 m / h, is low velocity impact. In low velocity impact , crash-box is one of the most important absorbing crash energy parts, through its own compressive deformation to absorb collision energy [9,10]. Position of crash-box in the bodywork is given in Fig.…”

Energy absorbing component of bumper equipped at the front end of a car, is one of the most important automotive parts for crash energy absorption. It usually was made a mental thin walled tube. In the paper, automobile energy absorbing component at low-velocity impact was studied by using Finite Element Method. The FE model of the tube was builded by comparing the five cross section shape . Results show that the impact peak load and maximum energy absorption have certain effect to energy-absorbing component with different the cross section shape.

“…To comply with such standards, it may be necessary for designers to employ materials with good energy absorption properties, either as an integral part of the interior structure, or as local countermeasure devices to protect occupants from isolated hard points. Aluminium honeycomb is one material with a proven track record in such applications [3].…”

This paper describes an investigation into the localized impact response of aluminium honeycombs and sandwich panels from the perspective of their use in occupant head protection applications. A programme of quasi-static and dynamic low-velocity impact testing using a hemispheric 'head form' impactor is described. From this, design data is presented in terms of acceleration histories and head injury criterion values. Furthermore, a simple analytical model is described for predicting acceleration histories for preliminary design purposes.

The design of a novel chassis solution for a land speed record streamliner, the Buckeye Bullet 2, which represents an evolution of the vehicle that recently set various records in the electric vehicle classes is addressed in this paper. Various architectures for a lightweight solution are investigated considered. The reference chassis design of the Buckeye Bullet consists of a steel space frame structure, for which alternative candidate solutions are investigated. These include several combinations of aluminium honeycomb sandwich panels and carbon fibre composite skins and a composite monocoque structure. A high-speed streamliner requires a chassis that is stiff in both torsion and bending, especially in transversal direction, in order to avoid undesired vibrations that can compromise vehicle handling. Thus, the various solutions are compared on the basis of mass, stiffness and eigenfrequencies. Finally, this paper investigates chassis strength with respect to torsional and bending loads that produce critical stresses for the reference structure and for operative loads
