Objective:
The goal of this project was to create up to four qualified Navy Standard Bookend Shock Test Fixtures for a range of component weights and sizes to be used on Lightweight and Medium-weight Shock Test Machines. The objective was to reduce cost and schedule associated with test fixture development for all shock hardened U.S. Navy ships.
Summary:
The following steps were taken to accomplish the goal:
- Review bookend test fixture designs used and determine sizes / weights to support
- Determine common interfaces, investigate standard materials and installations
- Design, model and analyze test fixtures, compare analyses to previously approved designs
- Perform shock testing and compare to the analysis
- Review designs with the Navy Delegated Approval Authority (NAVSEA 05P1)
- Create Navy Standard Drawings of each bookend test fixture for inclusion in the next revision of MIL-DTL-901
Key Deliverables / Benefits:
- Final Report with recommendations
- Small, medium, and large bookend test fixtures were designed and validated through this yearlong effort of analysis and shock testing.
- Fabrication drawings and AutoCAD files for the fixtures were provided to NSWCCD for inclusion in the next revision of MIL-DTL-901.
- The bookend fixture designs and drawings will be available for use by all Navy approved Shock Test Facilities and may eliminate up to $10,000 per shock test by avoiding the associated labor, fabrication and approval process for bookend fixtures. The standard bookend fixtures will promote commonality across shock test facilities and improve efficiency for Navy environmental qualification test programs.
