Abstract

The beam present an optimal distribution of flexural constraints. The stable loading arrangement provided by the design has the load application point below the supports points and finds application in railway vehicle wheel loading. The central loaded section consists of a curved, symmetrical tapering beam which is bi-concave upwards. The geometric properties of the shape include a fixed range of ratios of inferior profile radius (R) to semi-length (L). The central underslung portion contains an ellipsoidal opening symmetrically related to the semi-length. In and of length parametrically related to the semi-lenght. In other variations, the top surface is horizontal and coplanar with the support points.
