Seattle Safety / ZSE ServoSled System with a nominal force up to 3.1 MN
The SESA acceleration sled system has been named, ServoSled, and this
system is the next step forward in sled technology. Like the conventional servo-hydraulic sleds, the system uses computer- controlled servo-valves to
form the pulse, but the fluid does not itself push the sled. Instead the servo-hydraulic system modulates the pressure applied to a hydraulic friction
brake which controls the net force and energy applied to the sled by a pneumatic actuator. The advantage of this approach is that standard industrial
single-stage servo-valves and small hydraulic power units can be used with resulting higher frequency response and low cost, complexity, and maintenance.
