Analysis of Transverse Vibration of Circular Plates with an Elastically Mounted Mass Based on Combination of GDQM and FEM Ping Lia, Ying Wang Department of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang 471003, China aeappol@163.com Key words: GDQM; Finite Element Method; Circular Plates; Free Vibration Abstract.
Mp is the plate’s mass, ρ the density of the material, and D the flexural rigidity. k1 is the spring constant at the center and m is the mass of the object.
The annular plate has an outer radius a, inner radius b, radius proportion α＝b/a, and the density of the material ρ. γ is the density’s proportion between the mass and the plate, γ=1.
