Vibration of a clamped plate with concentrated mass and spring attachments

摘要: Abstract Vibrations of clamped plates with concentrated mass and spring attachments are investigated experimentally by using a modal analysis technique numerically mixed boundary-finite element method. Attachments modeled lumped parameters, the effects stiffness on plate vibration studied. Two dimensionless parameters identified as having major influence free modes, so-called parameter which relates point to plate, plate. The well effect position attachment modes studied over wide range parameters. results demonstrate usefulness experimental in validating theoretical models. A number limitations caused non-linear behavior system modeling single-degree-of-freedom systems discussed.
