Dynamics of a suspended cable under moving masses / Muscolino, G; Sofi, Alba. - (2003), pp. 109-116. (Intervento presentato al convegno Fifth International Symposium on CABLE DYNAMICS tenutosi a Santa Margherita Ligure, Italy nel September 15-18).
abstract:
In this paper, nonlinear in-plane vibrations of a suspended cable carrying moving masses are
investigated. A consistent model of the cable/mass system including both geometrical nonlinearities
and convective acceleration effects is adopted. Following the well-known “mode acceleration”
method, an improved series representation of the response is derived by adding the so-called “quasistatic”
solution to the conventional series expansion in terms of eigenfunctions of the associated
linear problem. Numerical results presented in the paper demonstrate the convergence of the
improved series, which enables to capture with very few terms the abrupt changes of cable profile at
the contact points between the masses and the cable.
