EFFECT OF A MOVING SYSTEM OF FORCES ON A BEAM LYING ON AN ELASTIC BASE

DEISTVIE DVIZHUSHCHEISYA SISTEMY SIL NA BALKU, LEZHASHCHUYU NAUPRUGOM OSNOVANII

Steady-state vibrations of an infinite beam supported by a Winkler base are investigated for the case when an infinite system of identical forces moves along the beam at a constant velocity. In addition, a uniformly distributed load pressing the beam to the base acts on the beam. A computation algorithm is worked out taking into account the possibility of the appearance of a zone of separation of the beam from the base. The relationship between problem parameters accompanying the onset of such a zone is made clear. Results of numerical calculations for a wide range of parameters are presented. The possiblity of the loss of stability by the beam from the plane in which the moving load acts is investigated. An example close to railroad track parameters is given.
