Stability of Two Oscillators on an E-B Beam.

摘要

The stability program of two oscillators moving uniformly along a Euler-Bernoulli beam on a visco-elastic foundation is studied. It is assumed that the masses and the beam are in continuous contact and that the velocity of the oscillators exceeds the minimum phase velocity of waves in the supported beam. Stability regions are found. It is shown that a range of velocities exists for which unstable vibrations of the two oscillators will occur for all elastic-inertial properties.
