**A Three-Dimensional Dynamic Simulator for the Pantograph**

frame structures can undergo significant catenary action under column loss scenarios in both steel [7,8] and concrete [9–12] systems. For example, in an interior column loss scenario shown in Figure1, span lengths are effectively doubled and subjected to significant load increases from the columns above over a very short time. The flexural capacity of the beams is likely inadequate to solely... - the quasi-static approach: the shape and tension of mooring lines are derived from catenary formulations. The catenary formulations account for the weight and the axial stiffness of the lines, they do not account for the inertia, the current and the wave forces. The mooring lines are described in 2D, in a vertical plane through anchor and fairlead. - the dynamic approach: each mooring line

The pertinent mathematical model is particu larly simple and may be analyzed as an isoperimetric prob lem of the calculus of variations^. When the assumption of inelasticity is abandoned (and thus the string is allowed to elongate), determination of the equilibrium configura tion is substantially more difficult

## Assumptions Of A Catenary Pdf

The changing law of internal forces during the whole deformation development process was analyzed. The process was divided into five stages based on the internal force state of the beam and the assumptions of internal force relationship of five stages were proposed. Then, the formulas for

- certain initial assumptions, the currents flowing through all feeding and return conductors are approximated as linear functions of the train current in the simplified model. The computational demand can thus be reduced at the expense of certain degree of accuracy. With the impedance of feeding conductors, the train voltage is then estimated. The probability density function (pdf) of the train
- catenary by an "equivalent" horizontal line located at the "average height": Hav = H For catenary lines with large sags these assumptions are questionable, as there are field components along the propagation direction, albeit small, which preclude the existence of a TEM mode. Even when these components are neglected, the distributed circuit parameters vary along the line span, as the
