IDENTIFYING FORCES IN A INTERFACE BETWEEN A BODY AND A SUSPENSION OF A VEHICLE

Forces in a vehicle interface between the suspension and a body are identified. Rather than using many or all strain gauges, some more easily and rapidly installed acceleration sensors are instead used to measure local deformation. To remove or reduce the effects of rigid-body motion captured by accelerometers, an inertial measurement unit is also used. The forces are estimated from a behavior model accounting for both rigid and flexible motions.
