The crash box plays a key role in the car's low speed crash performance, and also important for high speed crash. Currently, the styling design goes ahead of structure design in a car's development, leading to the poor performance of the crash box which is designed under the constraint of styling. In this paper, a new method is put forward for coupling the design of styling and crash box's crash performance in the styling design phase of an B-class car. In this method, basing on the crash load case, the crash box's section force target is deduce by its energy absorption ratio. Then the design parameter is deduced. With this method, the compatibility between the styling and crash performance is evaluated during the early phase of the car's development. A compatible design of styling and crash performance can be acquired by the optimization of styling and under this method. Finally, the B-class car's crash result is shown in this paper for the verification of the effectiveness and engineeringfeasibility of this method. © Springer-Verlag 2013. Source

According to the structural characteristics of a domestic hybrid electric vehicle (HEV), a simulation model to describe the rear-end collision is established based on the finite element analysis to analyze and optimize the safety of the vehicle. Then, the bending mode, the torsional mode and the torsional stiffness of the HEV are calculated and compared with those of the prototype vehicle. Moreover, by controlling the displacements in both the X direction of power battery box and the Z direction of hook at the upper backrest of back row seat, the existing structure and safety of the whole-vehicle rear-end collision are optimized and redesigned. The results show that the HEV comes up to the standard of conventional vehicles in terms of bending mode, torsional mode and torsional stiffness, etc. The rear-end collision test of a real vehicle proves that the improved security structure meets the design requirements well.

The motion vector relation of a car was built under the action of crosswind in general case, a multi-body dynamics model of the car was established by using ADAMS Car. Based on the external flow field analyses of body, the discrete aerodynamic six-component coefficients were translated into continuous aerodynamic forces by using the vector relation, the crosswind load was exerted in real time according to yaw angle of body; the transient crosswind stability simulation was executed according to ESV regulations. The influence rules of simplified aerodynamic load on crosswind stability were discussed, the quantitative simulation results are agree with the flow field qualitative analyses, which proves the correctness and reliability of the method. © 2016, China Mechanical Engineering Magazine Office.

Single-crystalline titanium nitride nanowires (TiN NWs) have been directly synthesized by a novel chemical vapor deposition (CVD) method and used as efficient catalysts for hydrogen evolution reaction (HER) for the first time. Electrochemical tests reveal good HER performance of TiN NWs, with a low overpotential of 92 mV at 1 mA cm-2 and a Tafel slope of 54 mV dec-1. After 20 000 cycles and 100 h durability test also in acidic media, the current density remains nearly unchanged, revealing the good chemical stability of the as-synthesized TiN NWs for HER. © The Royal Society of Chemistry 2016.
