Abstract
Bus superstructures may soon be subject to new rollover safety
requirements. Increased rollover safety must be achieved with
minimum weight or cost penalty; hence, optimisation has a
significant practical relevance.
This paper demonstrates the possibility of predicting the
collapse performance of a bus superstructure by a completely
theoretical model. The work described also created a basis for the
option offered by the new regulations that allows type approval by
calculation combined with some component tests. It also shows how a
safety structure can be optimised from the weight or cost point of
view by means of a special computer program.
