Vertical Vibration of Two Axle Railway Vehicle

The vertical vibration of the two axle vehicle has been solved analytically using the model of rigid rectangular plate with asymmetrically load distribution related to geometrical symmetry axes of central plane. Vertical displacements are solved for various cases of asymmetry, under kinematic excitation of the system with three degrees of freedom. The displacement of the centre of gravity and rotations to central axes are solved. The elastic support of the plate is combined with parallel viscous dumper. The task of vibration analysis is defined generally (and solved analytically) and for further solution (or extended) SYMPACT, ADAMS or MEDINA etc. software are possible to use.
