Investigation of Vehicle Rear Under Run Protection Device (RUPD) Using Aluminium Foam

[摘要] Whenever the passenger cars meet with accidents with the heavy duty truck from rear, it will tend to penetrate under the truck bed called truck trailer under-ride crash. This is responsible for the thousands of accidents, causing severe injuries and spot death. This is mostly due to the lack of effective guarding system. The Present paper gives an importance on energy absorption mechanism of a Rear under Run Protection Device (RUPD) under crash effect of the truck. The aim of the study is to replace Steel RUPD with aluminum foam, which promises an improvement of vehicle crashworthiness as well as to reduce weight of the vehicle. The aluminum foam is selected due to the high specific strength and specific stiffness. This inborn character makes it a promising candidate in the modern lightweight structures in the automotive engineering which can contribute to the improvement of mileage in addition to safety of the occupants.
