Resonances in an Infinitely Long Cable on a Tensionless Non-Smooth Foundation: A Numerical Analysis Available to Purchase

When a semi-infinite cable resting on a bed of unilateral springs is subjected to a harmonic excitation, the motion of the touch-down-point (TDP), i.e., the point which separates the detached part of the cable from the laid part, and which is assumed to be unique in this paper, exhibits interesting resonant phenomena. These phenomena are studied numerically by means of a self-made finite element (FEM) code, and the effects of the non-linearity of the problem, such as, e.g., the bending of the resonance curves and the secondary resonances, are investigated in detail.
