Crash analysis of non-air-conditioned sleeper bus has been carried in present work. Using relevant automotive industry standards (052 and 119) bus dimensions are considered for design. Surface modeling technique is used to prepare computer aided model. Further the bus design is freeze using finite element analysis for different crash conditions as front impact, side impact and rear impact. Crash analysis of the proposed bus design is carried using Ansys Workbench. Using the outcomes from finite element analysis as stresses, deflections, internal and kinetic energies during various crash conditions are estimated. Mesh generator is used to mesh the complex bus model. The stress and deflection magnitudes of proposed bus model are in good agreement with the experimental results available in literature. Design improvements are made using the finite element analysis outcomes, observing the deformation patterns additional pillar members of suitable length are added to increase the dynamic crush and further enhance occupant safety during collisions.

Lightweight Structure

Racing a car involves high-speed and having high possibility to crash either among the racer or hitting the bench. Concerning the driver safety, impact structures such as nose cone is designed to absorb the race car kinetic energy to limit the decelerations acting on the human body. In this study, analysis of different type of nose cone material were conducted. The objective is to find the highest specific energy absorption (SEA) based on three different materials which are mild steel, aluminium and composite material. The nose cone was modelled using CATIA V5R16 while the crash simulation was done using LS-DYNA and LS-Prepost software with an average velocity of 80km/hour according to United States New Car Assessment Program (US-NCAP) frontal impact velocity and based on European Enhanced Vehicle-safety Committee.  The simulation results show that fiberglass E with thickness of 2.6 mm and lay-up configurations of [0°/30°/60°/90°/120°] give the highest internal energy and specific energy absorption of 41.28845 kJ and 6.9104 kJ/kg. This concludes that fiberglass E is a suitable material to build a lightweight structure compared to steel and aluminium.

The novel Fomichev plug described in this paper is of characteristic producing equal unit-reduction of wall thickness along its perforation section during seamless tube piercing, which designed on the base of the roll opening of Julong piercer, taking into account for both feed angle and toe angle of a cone type piercer. Then a 3-D thermal-mechanical coupled numerical simulation on performance characteristic of novel Fomichev plug is presented with the aid of commercial FE code MSC.SuperForm, according to practical process parameters of piercing and rolling for steel grade P91 on Julong piercer in Yangzhou Chengde Steel Pipe Co., Ltd. By comparison with conventional plugs, as FE simulation result shows that the new plug reduces the damage value of the workpiece, thus decreases the tendency of lamination defects. What’s more, the axial resistance of novel Fomichev plug is smaller than the conventional, which is in favor of biting condition and increases piercing efficiency. Furthermore, the newly-designed plug’s temperature field is more uniform, which can alleviate failure of piercing plug caused by overtop local temperature, prolong its working life, and improve the quality of hollow shells.
