The dynamic response of a spinning disk on a damped elastic foundation, subjected to a radially moving transverse load is presented. Classical plate theory is used in the current study. Both centrifugal force and flexural rigidity of the disk together with damping and foundation stiffness, attributable to the fluid flow around the disk, are considered in the governing equation.;A mixed analytic-numerical solution scheme modified from FAST1 is developed to compute the dynamic response of spinning disks subjected to space-fixed transverse loads. The response to radially moving loads is constructed through the application of periodic Green's functions. Both steady-state and transient responses of the disk to radially moving loads are studied. The result indicates that a radially moving transverse load excites the disk at all the harmonics of the input excitation. The effect of damping and foundation stiffness to disk responses is illustrated. |
