Front rail is a key assembly for the frontal impact of vehicle. In this work, based on information benchmark vehicles and high-strength steels, front rails are designed to improve crash performance vehicle reduce its structural mass (SM). First, finite element analysis (FEA) carried out, dynamic drop testings performed verify accuracy model. Then, sectional dimensions, materials thicknesses ten...

Due to their superior structural and mechanical properties, materials with negative Poisson’s ratio are of increasing interest research scholars, especially in fuel-efficient vehicles. In this work, a new concave I-shaped honeycomb structure is established by integrating the re-entrant hexagon beam structure, its characteristics energy absorption properties investigated. The effect parameters o...

Automotive manufacturers rely on rigorous testing and simulations to construct their vehicles durable safe in all aspects. One such vital factor is crash safety, otherwise known as crashworthiness. Crash tests are conventional forms of non-destructive methods validate the vehicle for its crashworthiness compatibility based different operating conditions. The frontal impact test most primary for...
