Abstract
A Constant Force Control methodology and system utilizing integrated sensors and unique control algorithms to determine required applied force to mitigate shock events in an adaptive energy absorption system, typically comprising of a spring and an adjustable energy absorber or damper element. By utilizing an expected acceleration profile and event duration for an anticipated shock event an acceleration amplitude can be determined from a measure impact velocity. From this and a measured payload mass a system controller can determine the force necessary to be applied by the energy absorber in order to stop the payload over the full desired length of the available energy absorber stroke in order to minimize the forces experienced by the payload.
