The structured parametric multibody model of the empty ŠKODA 21 Tr low-floor trolleybus is created using SIMPACK simulation tool. The basic SIMPACK Kinematics & Dynamics module and the SIMPACK Automotive+ module are used to create the ŠKODA 21 Tr trolleybus multibody model. In comparison with the multibody model created in alaska 2.3 simulation tool the multibody model is extended by the model of a steering mechanism and by the model of a driving mechanism. The trolleybus multibody model is supposed to be utilized for the simulations of driving manoeuvres (driving along a predefined path, e.g. a severe lane-change manoeuvre in compliance with ISO 3888-1), braking, slow front impact against a concrete wall, running over a large road unevenness and driving along a defined uneven road surface. The aim of the simulations is the calculation of time histories or frequency responses of kinematic and dynamic quantities describing the vehicle examined properties in the chosen operational situation.
