Optimisation of a Bus Superstructure From the Rollover Safety Point of View 856104
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.
