Cost Reduction of MILDTL901 E Shock Applications Meeting

Cost Reduction of MIL-DTL-901 E Shock Applications Meeting shock qualification requirements at lower cost Team: Ingalls Shipbuilding | Newport News Shipbuilding | NAVSEA | National Technical Systems | Hi-Test Laboratories | Trident Maritime Systems Problem Statement Solution/ Approach Shock testing has been a significant cost driver and schedule concern for acquisition programs for many years. The project team will focus on several aspects of shock testing that are potential cost saving initiatives. Utilize MIL-DTL-901 E to push old and new cost avoidance initiatives across the finish line and share results with the shock community through: • Navy Standard Drawings • Addendum to 901 E Project Benefits Deck Simulating Shock Machine (DSSM) Fixture Concept Design The lightweight fixture designs will allow for greater payload weight on the Lightweight Shock Machine. The medium weight fixture will provide time savings by reducing blow count. The DSSM fixture will provide the customer and test labs with the first 901 E approved test fixture. Medium Weight Fixture Concept Design Project ROI Using standard, pre-approved shock test fixtures will save $5 K to $10 K per test. Moving testing from the barge to a machine saves over $20 K per test. For a first-of-class ship, using standard test fixtures can save on the order of $1. 25 M. For a first-of-class ship, moving 100 shock tests from the barge to a machine can save on the order of $2 M.
