Skyhook Control Law Extension for Suspension with Nonlinear Spring Characteristics

This work aimed to improve the vehicle body stability and ride comfort of tracked military crew. For this purpose, magnetorheological fluid dampers were used. process has made theoretical model platform a semi-active suspension system. modification allows for application different control laws these systems. The usage continuous skyhook law assumes influence three fictitious viscous dampers. Their force in conceptual is replicated by real However, does not take into consideration nonlinear stiffness characteristics. In paper, been appropriately modified. takes nonlinearity Applying modified improves crew’s comfort. All goals had be introduced due modernization replacing torsion bars with spiral spring packages
