Abstract:
1. A system for impact simulator testing in the footwell region of a vehicle to enable more accurate lower leg injury criteria measurements by generating footwell intrusion, comprising: a sled buck; a footrest plane located on the sled buck; a pivot hinge located at the base of the footrest plane and upon which the footrest plane pivots; a slide plane allowing horizontal motion on the floor of the sled buck; a compressed fluid tank; a first timer-released solenoid valve fluidly coupled to the compressed fluid tank; a second timer-released solenoid valve fluidly coupled to the compressed fluid tank; a first piston-cylinder fluidly coupled to the first timer-released solenoid valve; a second piston-cylinder fluidly coupled to the second timer-released solenoid valve; a translational force block, upon which, when actuated, the second piston-cylinder places a horizontal force, and with which the translational force block is moved horizontally into the footrest plane; wherein a rotational motion is generated by a fluid flow from the compressed fluid tank to the first piston-cylinder, being actuated by the first timer-released solenoid valve and moving horizontally into the footrest plane, thereby creating the rotational motion to the footrest plane; and wherein a translational motion is generated by a fluid flow from the compressed fluid tank to the second piston-cylinder, being actuated by the second timer-released solenoid valve and creating the translational motion by moving the translational force block horizontally along the slide plane to the footrest plane.
