Abstract: A Railway Vehicle Air Brake System has been analysed by considering its system kinematics and fluid mechanics. The kinematic model is represented by a single degree of freedom equation of motion, yielding a formed solution. Air flow is assumed as incompressible and unsteady. Corrections for instantaneous mean density have been made and the Runge-kutta method of numerical integration has been used for solving the governing differential equation. Analytical results are in good agreement with the laboratory data.

Keywords: vehicle braking; brake performance assessment; fluid mechanics; kinematics; railway vehicles; air brakes; mathematical modelling; kinematic models.
