The active and passive safety of a vehicle is composed of several features, which have a very important role in engineering a coach or a bus.
The demand for a safe travel urged the bus industry to develope certain methods, through which a better quality and safer coach can be realized.
The main areas of this problem are harmonization among brake and steering systems, wheel suspension, arrangement of the driver's compartment in order to improve the ride characteristics and a detailed structural analysis of the whole skeleton /body/.
The analysis to be presented introduces a part of the whole development and engineering work at Ikarus Body- and Coach Building Works, and shows certain correlations among parameters determining the safety of a vehicle.
The analysing method to be dicussed is suitable for computer programs and has been proved by tests carried out at laboratory and test tracks, mainly in Hungary.
