Design and simulation of a rear underride protection device (RUPD)for heavy vehicles
Every year, thousands of deaths are recorded worldwide due to crashes of small cars with heavy trucks. The highest risk during collision of passengers’ car with a truck is the intrusion of passengers’ compartment under the heavy truck rear underride leading to cause fatal injuries to passengers....

| Summary: | Every year, thousands of deaths are recorded worldwide due to crashes of small cars with heavy
trucks. The highest risk during collision of passengers’ car with a truck is the intrusion of
passengers’ compartment under the heavy truck rear underride leading to cause fatal injuries to
passengers. Design of robust underride guard of truck is one of the significant factors that should
be taken into consideration within design and enhancement of truck chassis. In this study, a new
rear underride protection device (RUPD) based on FMVSS 223/224 regulations is developed to
enhance the crashworthiness and reduce passenger compartment intrusion under heavy trucks
during accident. Finite element simulation is utilised for performance analysis of the RUPD in LSDYNA.
The results showed that the new RUPD design enhanced the energy absorption by 68.87%
and reduced the occupant’s car deceleration by 66.116%. The new guard is able to avoid underride
of Toyota Yaris (2010) colliding at 45, 54 and 63 km/h compared with the normal guard that failed
under the same test conditions. |
