The present work concerns the analysis of the asymmetric displacement behaviour of the rear part of a motorcycle. Stylistic reasons led to the design of a vehicle with only one suspension located at the left side. Experimental tests performed on a circuit with seven obstacles along a straight line confirmed that the bending displacement is higher on the right side than on the left one. This work aims to perform a structural optimization of the components involved in the rear side of the motorcycle, in order to find a solution to the problem. A hybrid approach is applied: the force acting on the suspension and bending displacements at the rear side were simultaneously measured in working conditions, then a FEM model was set up, validated and applied for design optimization purposes. Both methodological aspects and applicative results are presented and discussed. Finally a solution in accordance with design specifics is proposed

Abstract
The present work concerns the analysis of the asymmetric displacement behaviour of the rear part of a motorcycle. Stylistic reasons led to the design of a vehicle with only one suspension located at the left side. Experimental tests performed on a circuit with seven obstacles along a straight line confirmed that the bending displacement is higher on the right side than on the left one. This work aims to perform a structural optimization of the components involved in the rear side of the motorcycle, in order to find a solution to the problem. A hybrid approach is applied: the force acting on the suspension and bending displacements at the rear side were simultaneously measured in working conditions, then a FEM model was set up, validated and applied for design optimization purposes. Both methodological aspects and applicative results are presented and discussed. Finally a solution in accordance with design specifics is proposedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
