The paper deals with the development of an analytical model for the symbolic computation of the stresses and the strains in a structure composed by spokes. Each spoke is connected to other spokes at the centre of the structure. The spoke tips that are far from the centre of the structure are connected to the ground by means of springs. Given the generalized forces acting at the centre of the structure, the internal forces acting inside the spokes (represented as beams) are computed symbolically. The analytical formulae referring to such internal forces are given for a structure composed by 3 spokes. A validation of the symbolic computation is performed both for the 3 and for the 5 spokes structure. The proposed symbolic computational method may be applied to structures composed by a generic number of spokes. The derived analytical formulae pertaining to the 3 spokes structure have been successfully employed for the design of an innovative six axes load cell.

Abstract

The paper deals with the development of an analytical model for the symbolic computation of the stresses and the strains in a structure composed by spokes. Each spoke is connected to other spokes at the centre of the structure. The spoke tips that are far from the centre of the structure are connected to the ground by means of springs. Given the generalized forces acting at the centre of the structure, the internal forces acting inside the spokes (represented as beams) are computed symbolically. The analytical formulae referring to such internal forces are given for a structure composed by 3 spokes. A validation of the symbolic computation is performed both for the 3 and for the 5 spokes structure. The proposed symbolic computational method may be applied to structures composed by a generic number of spokes. The derived analytical formulae pertaining to the 3 spokes structure have been successfully employed for the design of an innovative six axes load cell.
