The stability and smoothness of rolling stock running could be defined accurately by universal Sperling's comfort index. divergences variation index a passenger car under specific operating conditions gear are examining in this paper. Numerical simulations with independently rotating wheels various have been performing. Gained results showed that the particularly significant due to component os...

Abstract We investigate numerically the dynamical reactions of a moving wheelset model to real measured track irregularities. The background is examine whether dynamics are suitable as input inverse problem: determine true geometry from reactions. It known that method works well for vertical position rails but computed lateral often flawed. find motion may differ geometry. cases investigated cl...

The main topic of this article is the strength analysis selected bogie components – wheelset axle and frame. Axle calculations were based on analytical method conducted with different types materials. finite element was used for verification frame construction loads applied calculated according to PN-EN 13749 norm. a part suspended electric multiple unit which matter authors’ master thesis: „Th...
