Abstract

The article deals with the proper transverse oscillations of a beam with free edges while the conditions of support on an elastic base change, taking into account its own weight and the influenceof the attached mass m1. The problem of determining the forces in the beam is being solved taking into account the dynamic load F(t) applied at an arbitrary point d while the conditions for the support of a part of the beam on an elastic base change.The conditions that must be taken into account while analyzing the dynamic action of the structure under the influenceof variable loads in the case of changes in the conditions of support on an elastic base are formulated.
