Effects of support configuration on the parametric excitation of a plate

Abstract

The equations of motions of a classical thin plate moving over multiple supports are formulated based on Hamilton's principle and the assumed mode method. The supports are frictionless line supports spanning the entire or partial width of the plate with the plate being pushed or pulled over them. A feature of the present formulation is that its complexity does not increase with increased number of line supports. The effects of support length and eccentricity in the locations of the support are examined for various prescribed longitudinal excitations of the plate. © 1994.
