Vehicle-grade hardware must survive two distinct categories of mechanical stress: sustained vibration from road surfaces and engine harmonics, and sudden shock events from impacts, drops, and abrupt mechanical forces. Axiomtek platforms are validated to both.
IEC 60068-2-64 (Random Vibration) simulates the unpredictable, stochastic energy distribution of real vehicle motion — the kind that causes cumulative fatigue in solder joints, connectors, and mounting brackets over thousands of hours of operation. Unlike sine wave testing (IEC 60068-2-6), which finds resonance frequencies, random vibration testing proves long-term structural integrity under real-world conditions. It is the foundational standard on which automotive OEM-specific tests like ISO 16750-3 are built.
IEC 60068-2-27 (Shock) addresses a different failure mode: sudden, high-force events — a loader striking a rock face, a haul truck dropping its bucket, an implement hitting an obstruction. The standard applies a half-sine pulse (50G at 11 ms) to validate that peak G-force events won't cause immediate structural or component failure. Combined with MIL-STD-810H Methods 514.8 and 516.8, the platform is validated against both international civilian and U.S. military field-use criteria.
