Abstract: Detailed stress analyses were required of critical lifting fixture components used to support conformal sonar array assemblies in performance trials conducted in 2008 at the Naval Undersea Warfare Center's Seneca Lake Test Facility. The stress analyses were necessary to ensure that the lifting fixture had sufficient structural integrity for the handling and operational phases of the trials. The targeted structural integrity levels required compliance with a minimum safety factor for each of the specific components investigated. The minimum safety factor was set to 5.0 based on the yield stress of each component. The stress analyses examined key screwed connections and weldments that join the lifting fixture to the array modules. The safety factors for the current component designs were determined and compared to the minimum requirement.
