Abstract

Background. It is well known that one of the most dangerous types of road accidents with buses is a rollover. UNECE Regulation № 66 stipulates the requirements that must be satisfied by the structure of a multipassenger vehicle’s body. The specific shift-buses on truck chassis present a separate group of buses and are designed to be used in harsh climatic conditions. Therefore there is an urgent task consisting in assessment of buses’ passive safety in the entire temperature range at operating conditions. The paper justifies the choice of a range of temperature conditions for this type of buses that must be taken into account during structure design thereof.
Materials and methods. Research of shift-buses passive safety was made by the finite element method. Experimental dependences were obtained on the modern calibrated equipment.
Results. The authors obtained experimental dependencies of strength characteristics of the materials that are used in shift-buses structures on the temperature. The article presents thedeveloped detailed finite-element models of shift-buses structures. The work includes the results of the study of passive body safety in the temperature range at operating conditions.
Conclusions. The authors proved the necessity of estimating the passive safety of shift-buses’ structures in the entire temperature range at operating conditions.

Key words

passive safety, bus, body made of sandwich panels, effect of temperature conditions.
