Comments on “The high-frequency response of a plate carrying a concentrated mass/spring system” [and reply]

See ibid., vol. 213, p. 843-63 (1998), Dowel and Tang present an investigation observing the high-frequency response of a plate carrying a concentrated mass/spring system. An understanding of high-frequency dynamics in coupled structures can be expanded through this generic problem. Following closely Kubota et al. (1990), the authors perform an asymptotic modal analysis based upon the assumptions of small damping and a large number of modes in the plate. The results for spatial average vibration in the plate and for the vibration amplitude of the attached oscillator are expressed in closed form. Such simple expressions are of great engineering interest as they allow quick estimates of the severity of vibrations received by small objects mounted on plate-like structures; e.g., delicate electric equipment mounted on a ships hull.
