Abstract
In order to verify the validity of "the Detailed Equation," we conducted a full scale experiment. The Detailed Equation is an equation of the equilibrium of the forces that act on a railway vehicle, which is similar to an equation for solving the overturning problem of a rigid body, but the external forces and the displacement of the car body are taken into account in detail. In the full scale experiment, we loaded lateral force (assumed to be crosswind) on the test vehicle, and examined the behavior of the vehicle. As a result, it has been verified that the Detailed Equation is valid for evaluating the critical wind speed of overturning or the wheel unloading ratio.
