The present paper analyses the feasibility of designing a high performance vehicle suspension using a Shape Memory Alloy (SMA) composite material. In particular, the possibility of replacing spring and damper of a double wishbone suspension with a leaf spring constituted by a hybrid material made of a fiberglass and SMA is analysed. Reduction of unsprung masses weight, improved aerodynamics, simplification of suspension layout reprent the main advantages associated with this solution. The choice of the SMA and design of the composite material has been made based on both Finite Element Analysis simulations and experimental tests.

Abstract
The present paper analyses the feasibility of designing a high performance vehicle suspension using a Shape Memory Alloy (SMA) composite material. In particular, the possibility of replacing spring and damper of a double wishbone suspension with a leaf spring constituted by a hybrid material made of a fiberglass and SMA is analysed. Reduction of unsprung masses weight, improved aerodynamics, simplification of suspension layout reprent the main advantages associated with this solution. The choice of the SMA and design of the composite material has been made based on both Finite Element Analysis simulations and experimental tests.| File | Dimensione | Formato | |
