Development and Testing of a Hydropneumatic Suspension System on a USMC AAV7A1

Abstract

This report discusses development, fabrication, and testing of an externally mounted, in-arm hydropneumatic suspension system on a United States Marine Corp (USMC) tracked amphibious vehicle (model AAV7A1). The suspension system was developed for a 60,000 pound vehicle and tested for performance and durability at the USMC Amphibian Vehicle Test Branch. This report contains test data and analysis resulting from this testing, in Test Branch. This report contains test data and analysis resulting from this testing, in addition to contractor test results obtained. The contractor completed and documented in this report a feasibility effort to demonstrate retractability of this type suspension for future USMC amphibious vehicles. This report contains information on a digital ride quality meter fabricated by the contractor for use on this program. Testing under this program did not result in ride quality data being taken.
