Název v původním jazyce

Dynamic response comparison of the wheelset partly and fully sprung drive

Popis výsledku v původním jazyce

Presented work follows up to the study of the partly sprung drive nonlinear dynamic model, which was presented in Railways 2016 conference. This study was further developed and extended by the dynamic model of fully sprung drive. That enables the direct comparison of both models at the same loads and excitations. The reason of continuous work concerning this topic is the increasing influence of dynamic load effects. The main dynamic loads are caused by the acceleration, deceleration, passaging curves and furthermore by the vertical unevenness of the rails. This contribution deals with the comparison of the partly sprung and fully sprung drive. These two design solutions are common in design of today rail vehicles. The subject of investigation is their response during various drive situations generated by the roller test rig. The application of the roller test rig is based on the previously presented work. The reason is that both drive models are equally loaded and the comparison of their response is thus objective.
