Abstract
This paper discusses the initiative of implementing a GPU-based
numerical algorithm for studying various phenomena associated
with dynamics of a high-speed railway transport. The proposed
numerical algorithm for calculating a critical speed of the bogie is
based on the first Lyapunov number. Numerical algorithm is validated
by analytical results, derived for a simple model. A dynamic
model of a carriage connected to a new dual-wheelset flexible bogie
is studied for linear and dry friction damping. Numerical results
obtained by CPU, MPU and GPU approaches are compared and
appropriateness of these methods is discussed.
