Vibration Testing

Vibration testing is commonly used as a method to recreate the fatigue stresses that occur during the life of an engineered product or assembly. Many in-service product and component failures are caused by fatigue, but these are avoidable with appropriate validation or investigative laboratory vibration testing.

Smithers Rapra has experience in vibration testing across a wide range of industrial sectors, with knowledge of automotive, aerospace and defense standards and applications, including ASTM, SAE, NES, JIS, DEF STAN 00-35, MIL STD 810, RCTA DO 160 and BS EN 60068.

Vibration Combined with Climatic Conditions

Our extensive testing-experience has equipped us to support clients with requirements ranging from "test-ready", to more complex vibration testing projects where test method review, test stand development and monitoring is required.

Smithers Rapra also has expertise in vibration under adverse climatic conditions. We regularly undertake vibration testing combined with severe cold and hot conditions, utilizing free-standing climatic chambers or by designing and assembling a bespoke chamber to enclose a vibration table to suit a specific requirement. Typically for combined vibration and thermal testing chambers are 1m3 in volume with temperature range from -40°C to +210°C.
