“…And also vertical (z), longitudinal (x) and lateral (y) motions are shown in Figure 1. Chudzikiewicz presented a wider expression by giving equations for all kinds of motion and also creep in his study [13]. As wheelset moves to x and y directions hence mainly longitudinal and lateral are considered while z plays the motion with co-axes.…”

“…The outcome of such operation of vehicles is an increase in vehicle's effects on the track in the rail-wheel contact resulting in increased ride resistance, creep in the rail-wheel contact patch, speeding up the process of wear in the contact-pair as well as noise generation. At present, a variety of technical solutions for the vehicle bogie design as well as rail designs focused on decreasing of these negative effects exists [1][2][3][4][5]. Their use in smaller radius curves however, cannot give acceptable results and often causes complications in bogie design.…”

Tramways in cities often ride in track curves of a small radius, which is followed by an increased effect of the vehicle on the track. In the rail - wheel contact often occurs creep in longitudinal as well as in lateral direction, which causes increase of riding resistance, wear in rail – wheel contact and noise operation. Exactly with the aim to reduce these undesirable effects we designed a tram bogie with steered wheelsets and with the double wheel tread. This inventions are registered by authors under Utility Model Nr. u201609015 and Patent Application Nr. a201701589. Description of proposed process of passing vehicle through strongly curved track is given in this paper. A comparison of creep velocities in rail - wheel contact results obtained by computer multibody simulations for a tram vehicle riding through a S-curve are presented. Purposefulness of proposed invention is investigated by constructing vehicle ride resistance dependence to the track curve radius.

“…The placed vehicle(s) with adjusted size may release out-of-phase loading and reduces the repercussion phenomenon. Chudzikiewicz [6] explained a general conception and realization of a computer package that is MAT-LAB to identify railway vehicles dynamic behavior. Sezer et al [7] done vibration analysis and dynamic modeling using matrix laboratory software.…”

Vibration is an undesirable phenomenon of ground vehicles like locomotives and vibration control of vehicle suspension system is an active subject of research. The main aim of the present work is to modeling and analysis of locomotive system. The simplified equations for dynamical locomotive are firstly established. Then the dynamical nature of the locomotive without control is investigated, and also active control suspension and passive control suspension are compare and discussed. The obtained simulation shows that suspension of the locomotive with feedback control could decrease the locomotive vibration. According to the above control strategy along with angular acceleration it also reduces the possibility of vibration of the locomotive body, to improves the stability of vehicle operation.
