Webb15 jan. 2024 · The concept of the catenary feed used on railway lines (Figure 1), was developed in the late 1800s. In theory, it’s straightforward. A wire is strung between poles and naturally takes on the classic catenary shape defined by the hyperbolic-cosine trigonometric function (see Reference ). The word "catenary" is derived from the Latin word catēna, which means "chain". The English word "catenary" is usually attributed to Thomas Jefferson, who wrote in a letter to Thomas Paine on the construction of an arch for a bridge: I have lately received from Italy a treatise on the equilibrium of arches, by the … Visa mer In physics and geometry, a catenary is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve … Visa mer In free-hanging chains, the force exerted is uniform with respect to length of the chain, and so the chain follows the catenary curve. The same is true of a simple suspension bridge or "catenary bridge," where the roadway follows the cable. A Visa mer Model of chains and arches In the mathematical model the chain (or cord, cable, rope, string, etc.) is idealized by assuming that it is so thin that it can be regarded as a curve and that it is so flexible any force of tension exerted by the chain is parallel to the chain. … Visa mer Catenary arches are often used in the construction of kilns. To create the desired curve, the shape of a hanging chain of the desired dimensions is transferred to a form which is then used as a guide for the placement of bricks or other building material. Visa mer The catenary produced by gravity provides an advantage to heavy anchor rodes. An anchor rode (or anchor line) usually consists of chain or … Visa mer Equation The equation of a catenary in Cartesian coordinates has the form The Whewell equation for the catenary is Differentiating gives Visa mer Nonuniform chains If the density of the chain is variable then the analysis above can be adapted to produce equations for the curve given the density, or given the curve to find the density.

For train operation at 300 km/h (186 mph) a copper clad steel contact wire and a copper alloy contact wire are used.
A catenary is a system of overhead wires used to supply electricity to a locomotive, tram (streetcar), or light rail vehicle that is equipped with a pantograph. Unlike simple overhead wires, in which the uninsulated wire is attached by clamps to closely spaced crosswires supported by poles, catenary systems use at least two wires. The catenary or messenger wire is hung at a specific tension between line structures, and a second wire is held in Webb11 sep. 2003 · The solid line is the FEM result; the others are the approximated functions of catenary stiffness.
