Vibration Testing & Vibration Analysis

Vibration testing, vibration analysis and mechanical shock help attune automotive products for structural soundness and paramount vehicle perception using methods such as resonant searches and dwells, fixture resonance evaluation, custom fixture design and fabrication, reproduction of sample road and/or event data, shock response spectrum (SRS) testing, buzz, squeak, and rattle (BSR) testing and more.

Shaking Things Up with Vibration Testing Webinar | Top-11 FAQs of Vibration Testing

Our vibration testing labs across the U.S. — including Grand Rapids and Plymouth, Michigan; Cortland, New York; Lexington, Kentucky; and Boxborough, Massachusetts — come together to help Intertek offer automotive testing experience and expertise that is second to none. For example, electrodynamic (ED) shakers can be used for Accelerated Stress Testing (AST), Highly Accelerated Life Test (HALT) capabilities can be put into practice to arm products with ongoing reliability, and Failure Mode Verification Test (FMVT®) capabilities use an Intertek-patented resonance impact vibration pod in applications to uncover real-world failure modes to assist with reliability growth.

Additional capabilities include shock testing, vibration analysis, simulate environment chambers, data acquisition, custom test fixture controls and software, and more, helping you fill all your automotive testing and standard certification needs at one stop — Intertek.
