Streszczenie: W artykule omówiono najczęściej stosowane symulacje modeli obliczeniowych autobusów, w których stosuje się układy wieloczłonowe. Na początku, krótko omówiono problem dynamiki układów wieloczłonowych. A następnie, przedstawiono modele obliczeniowe dla testu łosia oraz czołowego uderzenia pojazdu poruszającego się z małą prędkością w betonową ścianę. Te sytuacje potraktowano, jako przykładowe podejścia do modelowania z zastosowaniem układów wieloczłonowych. Wyniki analiz takiego ujęcia modelowego oraz wyniki badań symulacyjnych przyczyniły się do rozwoju konstrukcji autobusów.Słowa kluczowe: symulacja układów wieloczłonowych, autobus, manewrowanie pojazdem, test łosia, uderzenie z małą prędkością SELECTED PROBLEMS IN BUS DEVELOPMENT SOLVED USING MULTIBODY SIMULATIONSSummary: The paper deals with the most frequent simulations with the calculation models of buses based on multibody approaches. At first, the term multibody dynamics is introduced in brief. Then simulations of a moose test and slow front impact against the concrete wall are given as examples of using multibody simulations applied in bus development.

The Triple Hybrid Hydrogen Bus project comprises research and development, implementation and a test operation of a city bus with hybrid electric propulsion using hydrogen fuel cells. The mass distribution and the total bus mass are rather different from common buses. This is, among others, the reason for investigating the bus driving stability. In order to obtain a tool for dynamic analysis, multibody models of the bus were created. Verification of multibody models was performed based on the comparison of simulation results and experimental measurements focused on handling behaviour of the bus. To perform the simulations two approaches were used. The first (original) one, at which the initial position of the bus multibody model at the beginning of the simulation of the manoeuvre depends on the bus motion trajectory, and the second (new) one, at which the initial position of the bus multibody model at the beginning of the simulation of the manoeuvre is set an equilibrium position.

“…Another possibility for the design engineer is to consider a detailed multibody model, making use of commercial multibody software packages, as it has been done using ADAMS ® in works by Rongshan et al (2010), Wu et al (2009), Vilela (2001) and Prado et al (2001) -this is currently a widely disseminated approach. By adopting these more complex models the engineer can get very accurate results for the vehicle dynamics response - Rill (2006) and Adamski et al (1999) describe in more detail how some of these multibody models work, showing the benefits of the flexibility they bring to the design engineer.…”

This text presents a new proposal for an overall ride and handling metric to be used to optimise vehicle performance through concurrent simulation models. The proposed metric has the intention to cover simultaneously the most relevant aspects of a passenger vehicle dynamic behaviour. The individual models for ride and handling have been validated against physical measurements in order to assure a reliable output. A numerical optimisation method is used to simultaneously evaluate the complete vehicle dynamic performance related to the single overall metric. The results show an effective way to improve the vehicle performance based on this new proposed metric, with gains in terms of reduction in development time and cost for new projects.
