Design of AMRL Impact Facility Sled, Propulsion Unit and Decelerator.
Abstract
The objective of this program was to develop the facility plans, goals, and specifications for an extension to the existing AMRL Impact Test Facility. The test system designed is to be used to conduct biomedical research related to impact and to investigate principles and techniques of impact protection. The conceptual design of three main facility elements was accomplished. The items designed included an air gun accelerator, a sled or carriage to support the test object and a hydraulic buffer type decelerator. The propulsion unit is capable of accelerating the sled carrying 2000 lb of payload to an impact velocity of 125 fps. The decelerator is capable of providing a peak deceleration level of 150 g. Variable pulse shapes are possible and provision is made for achieving multiple peak pulses. The maximum deceleration stroke is 6 ft.
