Mode Shape

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

Interferometry - Applications - Engineering and Applied Science
... Single-mode lasers employ etalons to suppress all optical cavity modes except the single one of interest ... first-order diffracted beam, 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 ...
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 ... KE = PE, Note that the overall amplitude of the mode shape cancels out from each side, always ...
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 ...
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 ...
Structural Dynamics - Modal Analysis - Energy Method
... possible 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 freedom system ... 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:

    I used to say: “there is a God-shaped hole in me.” For a long time I stressed the absence, the hole. Now I find it is the shape which has become more important.
    Salman Rushdie (b. 1948)

    If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.
    Henry Brooks Adams (1838–1918)
