dynamic analysis of double wishbone Front Suspension systems on sport motorcycles
Nonlinear Dynamics, 2018Co-Authors: Ciro Moreno Ramirez, Maria Tomasrodriguez, Simos A. EvangelouAbstract:In this paper, two alternative Front Suspension systems and their influence on motorcycle dynamics are investigated. Based on an existing motorcycle mathematical model, the Front end is modified to accommodate both Girder and Hossack Suspension systems. Both of them have in common a double wishbone design that varies the Front end geometry on certain manoeuvrings and, consequently, the machine’s behaviour. The kinematics of the two systems and their impact on the motorcycle performance is analysed and compared to the well known telescopic fork Suspension system. Stability study for both systems is carried out by means of root-loci methods, in which the main oscillation modes, weave and wobble, are studied and compared to the baseline model.

Dynamic analysis of double wishbone Front Suspension systems on sport motorcycles
Nonlinear Dynamics, 2018Co-Authors: Ciro Moreno Ramírez, M. Tomas-rodriguez, Simos A. EvangelouAbstract:In this paper, two alternative Front suspen-sion systems and their influence on motorcycle non-linear dynamics are investigated. Based on an existing high-fidelity motorcycle mathematical model, the Front end is modified to accommodate both Girder and Hos-sack Suspension systems. Both of them have in com-mon a double wishbone design that varies the Front end geometry on certain manoeuvrings and, consequently, the machine's behaviour. The kinematics of the two systems and their impact on the motorcycle perfor-mance are analysed and compared to the well-known telescopic fork Suspension system. Stability study for both systems is carried out by combination of nonlinear dynamical simulation and root-loci analysis methods.

Design of a double wishbone Front Suspension for an orchard–vineyard tractor: Kinematic analysis
Journal of Terramechanics, 2015Co-Authors: Stefano Uberti, Daniel Chindamo, Marco Gadola, Matteo C. Romano, Francesco GalliAbstract:Abstract This paper deals with the design and implementation of a double wishbone Front Suspension for a vineyard–orchard tractor, developed in conjunction with a major tractor brand. To date, independent Front Suspensions are only found on commercial tractors over 150 kW. A Front suspended axle is recognized as a popular option in improving tractor ride performance on larger vehicles. Despite their narrow track, vineyard–orchard tractors are required to have good lateral stability and stability on slopes (i.e. at least 28° rollover angle) and an extremely tight turning diameter for a 4WD vehicle (less than 7 m). The discussion is concered with retrofitting an existing vehicle with a double wishbone Front Suspension. This paper focuses on the layout and kinematic analysis phases of the design process. These were conducted in collaboration with the vehicle manufacturer to demonstrate Suspension feasibility in terms of available space and correct kinematic layout. The final kinematic turning diameter obtained is about 6.4 m, with a ±65 mm Suspension travel available. The roll centre height value is not very sensitive to steering (about −95 mm excursion in the Z axis from no-steer position to full steer).
