Abstract

A high fidelity nonlinear model of a sport motorcycle is modified to include interconnected suspension forces between the front and rear ends. The comfort and the suspensions efficiency have been studied for a wide range of interconnection stiffness and damping coefficients. An optimization of these coefficients is performed considering different possible mechanical implementations, going from a simple damping connection to full variable stiffness and damping coefficients depending on the speed. Finally the system is analyzed from the stability point of view to ensure that the oscillating modes are not strongly modified and the system stability is not compromised.
