چکیده مقاله
In this paper, the transverse vibration of a rectangular plate
with multiple line concentrated masses is investigated by
using differential quadrature element method (DQEM).
Governing equation and boundary and compatibility
conditions are formulated based on differential quadrature
rules. The boundary conditions are simply supported in the
direction of width of plate and arbitrary in the direction of
its length. The compatibility conditions at the position of
concentrated mass are assumed as the continuity of
transverse displacement, rotation and bending moment and
discontinuity in the transverse force due to the acceleration
of the concentrated mass. The effects of number, magnitude
and position of the masses and boundary conditions on the
value of natural frequency are investigated. The accuracy,
convergence and efficiency of the proposed method are
confirmed by comparing the obtained numerical results with
the exact solutions of the other researchers.
