Vibration tests verify product requirements and assess robustness for transport or use conditions. These five expert tips will help optimize your vibration testing process.
Detailed planning is crucial for efficient vibration testing. Specifications should include more than just standard references - operational status and acceptance criteria must be clearly defined. Review sample checklists: and .
Mount test objects as they would be in normal use. Fixtures should create stable connections without adding resonances. IEC 60068-2-47 provides excellent guidance on fixture design.
While acceleration describes random movement absolutely, displacement (visible to the eye) helps calculate mechanical stress. Contact us for an Excel tool to calculate displacement for sine vibration.
Sine tests use single frequencies sequentially, while random tests use multiple frequencies simultaneously. Random vibration typically better simulates real-world conditions. provides guidance on selecting appropriate test types.
Beyond basic pass/fail criteria, perform detailed inspections for hidden damage. Check electrical connectors with magnification and examine EMC gaskets for wear. This reveals issues not apparent during initial testing.
