LRU Vibration Fixture
LRU Vibration Fixture
This project involved the design and delivery of a custom vibration fixture used for testing Line Replaceable Units (LRUs) at an Indian Air Force Base Repair Depot. Based solely on the vibration bed's dimensions and mounting layout, a fully functional fixture was developed to meet military testing requirements.

Research
The process began by studying the vibration bed’s hole layout, standard testing procedures and the typical mass and mounting configurations of LRUs. Reference was taken from MIL-STD guidelines to ensure compatibility with defense-grade testing requirements and fixture stability under dynamic loading.

Design
Design
The fixture was designed in 3D CAD to align precisely with the vibration bed’s hole pattern, while allowing flexible mounting options for various LRU sizes. The structure was optimized for stiffness and balance to minimize unwanted resonance and ensure accurate test results.
