Transient response of a disk with discrete impedances from its decelerating boundary

Analyzed is transient response of an elastic disk from its decelerating boundary. Eigenfunctions of the bear disk are used as Galerkin trial functions to the disk with discrete masses and impedances in the form of a one-degree-of-freedom (1-dof) oscillator. The oscillator mass models a module connected to the disk and the spring models the connecting isolation stiffness. For a fixed oscillator mass, except for very weak springs, stiffness mostly raises transmissibility of deceleration from disk to mass.
