Abstract
A method for configuring a hydraulic actuator to provide energy dissipation capabilities during low energy collisions while controlling energy dissipation during high energy collisions comprises biasing a valve member towards a closed position with a resilient member having a rigidity of between 600 and 1500 lbs/in, applying a low preload to the resilient member, and restricting the flow of fluid by using a stop to limit movement of the valve member away from the closed position.
