Abstract: Various vibrations occur in vehicles, which are generated by the vehicle's equipment or by the road itself. Several studies have been carried out on the investigation of vibrations in passenger cars or different purpose trucks, but there is little literature available on the analysis of special superstructure vehicles such as fire trucks. During our research therefore a simulation model for analyzing the vibrations of a double-cabin special fire truck was created. The main purpose of our research is investigating their effects on people traveling in fire-fighting vehicles. In this paper the developed model and the computer simulation using it is presented. With our results we want to draw the attention to the importance of the topic and to help the safe operation of fire-fighting vehicles.

Keywords: Double cabin fire truck, firefighter crew, vibrations, numerical simulation
