Mode Shape

Some articles on mode, mode shape, mode shapes, modes, shape:

Eigentone - Nodes
... In a one dimensional system at a given mode the vibration will have nodes, or places where the displacement is always zero ... These nodes correspond to points in the mode shape where the mode shape is zero ... Since the vibration of a system is given by the mode shape multiplied by a time function, the displacement of the node points remain zero at all times ...
Vibration - Multiple Degrees of Freedom Systems and Mode Shapes - Eigenvalue Problem
... These eigenvectors represent the mode shapes of the system ... The two mode shapes for the respective natural frequencies are given as Since the system is a 2 DOF system, there are two modes with their respective natural ... The mode shape vectors are not the absolute motion, but just describe relative motion of the degrees of freedom ...
Rayleigh-Ritz Method
... two lumped springs and two lumped masses, and only two mode shapes are assumed ... A mode shape is assumed for the system, with two terms, one of which is weighted by a factor B, e.g ... so, since KE = PE, Note that the overall amplitude of the mode shape cancels out from each side, always ...
Interferometry - Applications - Engineering and Applied Science
... Single-mode lasers employ etalons to suppress all optical cavity modes except the single one of interest ... however, is modified to match the desired shape of the test surface ... If a mode-locked laser is modulated to form a train of pulses, its spectrum is seen to consist of the carrier frequency surrounded by a closely spaced comb of optical sideband frequencies with a spacing equal ...
Structural Dynamics - Modal Analysis - Energy Method
... to calculate the frequency of different mode shape of system manually by the energy method ... For a given mode shape of a multiple degree of freedom system you can find an "equivalent" mass, stiffness and applied force for a single degree of ... For simple structures the basic mode shapes can be found by inspection, but it is not a conservative method ...

Famous quotes containing the words shape and/or mode:

    “Must a name mean something?” Alice asked doubtfully.
    “Of course it must,” Humpty Dumpty said with a short laugh: “my name means the shape I am—and a good handsome shape it is, too. With a name like yours, you might be any shape, almost.”
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    Almost any mode of observation will be successful at last, for what is most wanted is method.
    Henry David Thoreau (1817–1862)
