Wind-tunnel modelling of the phenomenon of railway wagons rolling over under strong crosswind action

Agnieszka Porowska

Abstrakt

This paper deals with the derivation of similarity criteria for the phenomenon of railway wagons rolling over when exposed to strong crosswinds. Utilizing these criteria, the authorial method for the determination of the aerodynamic coefficient of the rollover moment is also presented in the paper.
