RTCA DO-160 Section 7 Shock and Vibration Testing
The RTCA DO-160 standard is a set of guidelines designed to ensure that aviation electronic equipment can withstand the harsh environmental conditions encountered during flight. Specifically, Section 7 focuses on shock and vibration testing, which are critical for ensuring the durability and reliability of avionics in military applications.
In military environments, electronic devices often face extreme shocks and vibrations due to aircraft maneuvers, gunfire impacts, and operational stresses. The objective of this test is to verify that equipment can function correctly under these conditions without sustaining damage or degradation in performance. This testing aligns with international standards such as ISO 2631-1:2019 for human exposure and EN 45578:2005 for shock spectra.
The test involves subjecting the equipment to controlled shocks and vibrations that simulate real-world conditions. The apparatus used in this testing includes shaker tables, drop towers, and other specialized hardware capable of generating precise shock and vibration profiles. Acceptance criteria are strictly defined by the RTCA standards, ensuring consistency across different manufacturers.
RTCA DO-160 Section 7 is particularly important for military applications because it ensures that equipment can operate reliably in high-stress environments. This testing is not only about mechanical durability but also about maintaining electrical integrity and operational parameters under extreme conditions.
The process involves rigorous preparation of the test specimen, including mounting it on a shaker table or similar device. The specimen must be secured to ensure it does not move during the tests. Shock pulses are typically generated by dropping weights onto the test article or using piezoelectric actuators. Vibration testing is achieved through frequency sweeps over a range defined in the standard.
After each test, thorough inspection and functional checks are performed to determine if the equipment has met the acceptance criteria. If any failures occur, the equipment must be repaired and retested until all passes are successful.
The results of this testing provide critical data for both manufacturers and end-users regarding the reliability and durability of avionics under military conditions. This information is essential for decision-making in procurement processes, ensuring that only robust and reliable components are used in critical systems.
