METHOD OF DYNAMIC RESPONSE ANALYSIS FOR RAILWAY ROLLING STOCK AND RAIL TRACK INTERACTION

摘要

FIELD: transportation.;SUBSTANCE: analysis of dynamic railway rolling stock and rail track interaction response is based on the application of reversing principle. One subject of inquiry is represented as a vehicle or a set of components equipped with instrumentation, testing devices and simulating equipment for different types of environmental stress applied to the vehicle during movement. It is fixed at the place of testing and disturbing pulse is communicated to this vehicle from the side of wheel pair interacting with the observed rail track. Running stock is represented as an "endless" rail track climbing on wheel and consisting of a set of standard rails. Rail track interacts with vehicle wheel on horizontal section of running rail track where rail track foundation resilience, inclination simulation and rail elevations can be adjusted. Intensity and direction of force interaction between wheel and rail can be also adjusted on this section. In this case, minimum length of this section corresponds to a standard rail length.;EFFECT: improvement of effective loads accuracy.
