Analiza Drgań Wieszara Cięgnowego Jako Modelu Kolejowej Sieci Trakcyjnej Obciążonej Ruchem Pantografów

Abstract: Zwiększenie prędkości jazdy pociągów i rozwój kolei dużych prędkości spowodowały wyraźny wzrost zainteresowania problemami dynamiki kolejowych sieci trakcyjnych. W ostatnich latach pojawiło się w literaturze zagranicznej wiele nowych publikacji przedstawiających zaawansowane numerycznie metody symulacji drgań górnej sieci jezdnej i pantografów. W Polsce temat ten jest stosunkowo mało znany, stąd jednym z celów pracy jest przegląd literatury na temat metod modelowania sieci trakcyjnych. Celem zasadniczym jest p… Show more

“…Pantographs are treated as flat dynamic systems with two degrees of freedom (Figure 3), but they can be easily expanded into systems with several degrees of freedom. In contrast to the initial model described in [5] and [6], the pantograph base is not fixed, its vertical movement is determined by the vibrations of the rail vehicle at the theoretical points of contact between subsystems (1) and (2). It has been assumed, therefore, that the vertical movement of the pantograph base is described by functions p ( ) i ̇p ( ) defining the displacement and speed of vibration at the contact point , which is also the pantograph number.…”

“…3. This model is analogous to that described in detail in [5] and [6] but contains minor modifications in the definition of suspension lines and pantographs. The upper overhead contact line, similar to the initial model, is a towing hitch consisting of a multi-span carrier rope and a contact wire which is suspended to the rope by means of hangers.…”

“…Taking the described phenomena into account in the catenary computational model leads to a geometrically non-linear problem, consequently, the numerical integration scheme of the equations of motion becomes more complicated. Th e authors have proposed in [2] a method for solving non-linear equations of motion, which is based on an iterative determination of the non-linear forces compensating the infl uence of droppers up to zero, for the droppers which are identifi ed as subjected to compression in a given calculation step. Identifi cation of such droppers is performed on the basis of an observation of the relative displacement of both ends of each dropper.…”
