This paper describes an investigation of the effect of cross winds on train dynamic systems. It considers the nature of the fluctuating cross wind and how such cross winds produce fluctuating forces. A simple method for calculating the wind time history at the position of a moving vehicle is firstly

A semi-empirical model is described for predicting unsteady aerodynamic forces on arbitrary airfoils under mildly stalled and unstalled conditions. Aerodynamic forces are modelled using second-order ordinary differential equations for lift and moment with airfoil motion as the input. This model is s
