Optimisation of the Omnibus Roll Cage Structure

Summary

Improvement of vehicle stability and crashworthiness to reduce rollover and to provide increased occupant protection in the event of rollover requires that the effects of design parameters on vehicle rollover propensity are thoroughly understood. Improvement of rollover characteristics of buses currently requires extensive experimentation and considerable resources associated with rollover destruction of experimental bus structures. This research project presents an alternative approach to enhancing rollover design of buses based on experimental and analytical modal analysis. Inherent structural dynamic characteristics of the bus roll cage structure have been identified and tailored through global and local design sensitivity studies with respect to the overall rollover stability of the bus and its rollover strength.
