Abstract
Vertical dynamic properties of the ˇSKODA 21 Tr low-floor trolleybus were investigated on an artificial test track
when driving with a real vehicle and when simulating driving with a multibody model along a virtual test track.
Driving along the artificial test track was aimed to determine vertical dynamic properties of the real trolleybus and
on the basis of them to verify computer trolleybus models. Time histories and extreme values of the air springs relative
deflections are the monitored quantities. Due to differences of the experiments and the computer simulations
results the influences of the characteristics of the spring-damper structural elements of the axles suspension and
the radial characteristics of the tires used in the trolleybus multibody model on the extreme values of the monitored
quantities are evaluated.
