Abstract
A vehicle body contour-based derailment detection method for a rail vehicle, including: measuring distances between measuring points and rails through a range finder mounted on an underframe of a vehicle body, and calculating a transverse displacement of the current vehicle body in a vehicle body coordinate system; measuring an inclination angle of the current vehicle body in the vehicle body coordinate system through an inclination sensor on the vehicle body; with reference to a size of the vehicle body and distribution positions of the measuring points, as well as the transverse displacement of the current vehicle body in the vehicle body coordinate system and the inclination angle of the vehicle body in the vehicle body coordinate system, obtaining a dynamic outer contour of the vehicle body in the vehicle body coordinate system and converting it into a dynamic outer contour in the rail coordinate system.
