The application of computer simulations at the american bus design
Polach P., Hajžman M., Jankovec J.
pages 107 - +12p., full text

ŠKODA VÝZKUM s.r.o. cooperated at the development of the NEOPLAN RQ low-floor bus intended for the Boston city (the United States). Multibody models and finite element models of the bus were utilized in the stage of the bus design. The multibody models of the bus were created in the alaska simulation tool and the simulations of running over the large road unevenness represented by the artificial obstacles were aimed at determining forces acting in the bus suspension elements. Time histories of the forces calculated using multibody models were used as the input data of the bus finite element models. Utilizing the finite element models created in the COSMOS/M software the critical places of the bus body structure from the point of view of high stresses were determined. At the measurement with the real bus prototype these places were equipped with strain gauges.
