RIDE COMFORT AND ROAD HOLDING OF A 2-DOF VEHICLE TRAVELLING ON A RANDOMLY PROFILED ROAD

The suspension of a two-degree-of-freedom (2-dof) vehicle travelling on a randomly corrugated road is optimized with respect to both road holding and ride comfort. Optimal comfort is defined as a minimum mean value of the largest maxima of a stationary Gaussian random process. This process is the vertical vehicle seat acceleration weighted with respect to human sensitivity (ISO 2631). Optimal road holding is defined as a minimum probability that the road-wheel contact force will be smaller than a given level. This contact force is conceived as another stationary Gaussian random process. The two criteria are synthesized and the suspension system is optimized with respect to the joint criterion obtained. One restriction accounted for is the limited working space of the vehicle suspension.(a) /TRRL/
