“…Addressing this shortcoming, Ref. [6] propose the separate model method to calculate the pre-sag of the messenger wire and the lengths of droppers. This method separates the catenary into two sub-systems, namely the messenger wire system and the contact wire-dropper system.…”

“…Jest wyznaczana w sposób statyczny, z wykorzystaniem metody elementów skończonych do modelowania sieci jezdnej. W kolejnej pracy [5], Wu i Brennan rozbudowali model zastępując sztywność statyczną więzi sprężystej tzw. sztywnością dynamiczną, która wyznaczana jest na podstawie analizy drgań wieloprzęsłowej struny o cią-głym rozkładzie masy, stałym naciągu i podparciu punktowym za pomocą więzi sprężystych.…”

“…The catenary system can be represented in a simple form by its spatial static stiffness variation (Wu and Brennan, 1998;Wu and Brennan, 1999), however, this simple representation does not allow satisfactory inclusion of components such as droppers or the phenomena of wave reflections in the system. An improved approach in which these can be represented is to model the contact and catenary wires as Euler-Bernoulli beams, with forces applied at discrete locations to simulate the dynamic boundary conditions; stiffness and damping properties of components such as droppers and registration arms can also be included (Bucca and Collina, 2007).…”
