ECE R66 Simulation Accreditation Study with RADIOSS

A rollover incident is one of the most fatal case among the accident scenarios for coach type vehicles. The hazard of it makes the rollover resistance an important parameter for the design of the superstructure of the bus. In order to decrease the fatality, ECE R 66 regulations is in operation at Europe. The regulation describes certain test conditions and checks the intrusions to the residual space for the approval. By the development of the technology at computing systems, computational mechanics had became quite practical and trustworthy. The type approval for the ECE R66 can be obtained by computer simulation without testing. At this work, the simulation method of the rollover will be derived with Nonlinear Explicit Method using HyperWorks software package. The aim of the work is to describe the realistic model preparation having regard to practicality and decrease the computational expenses for the RADIOSS solver.
