Expert Dynamic Testing Services | Vibration, Shock & Fatigue

Dynamic testing evaluates how a product, component, or assembly performs when exposed to motion-based forces such as vibration, impact, repeated loading, or operational stress. For example, an automotive control module may be mounted to a vibration shaker and tested against random vibration profiles to identify resonance, fatigue, loose connections, or durability issues before production.

Dynamic testing helps reveal weaknesses that may not appear during static inspection or basic functional checks. It can identify resonance, cracking, fastener loosening, solder fatigue, deformation, and performance drift under realistic loading. Manufacturers use these results to improve designs, reduce warranty costs, document quality, and support safer product launches across industries such as automotive, aerospace, medical devices, and equipment.

Vibration testing focuses on continuous or repeated motion inputs, such as random vibration, sine sweeps, or sine-on-random profiles that simulate transportation or operating environments. Mechanical shock testing evaluates sudden high-force events like drops, impacts, handling shocks, or abrupt operational loads. Both are often used together to understand whether a product can survive real-world dynamic conditions.

Fatigue testing applies repeated stress cycles to determine how long a material, component, or assembly can perform before cracking, loosening, or failing. Cyclic fatigue testing is especially useful for products exposed to repeated loading and unloading, such as equipment brackets, tools, structural components, and assemblies. Results support durability targets, design improvements, and life expectancy estimates.

B83 Testing & Engineering serves a wide range of industries, including automotive, railroad, agricultural equipment, construction equipment, professional tools, medical devices and machines, electrical power controls, consumer products, aerospace, aviation, defense, packaging, data centers, power generation, mining, forestry, off-road, and naval applications. Testing programs can be adapted to product-specific requirements and operating environments.

A typical program begins with your product requirements, standards, use environment, loads, and pass/fail criteria. B83 then reviews fixture needs, instrumentation, sample constraints, and target profiles before testing. The lab may run vibration, shock, fatigue, RPC field data replication, or related procedures, then provide data and reporting to support engineering decisions.

Yes. B83 Testing & Engineering offers unique fixture design and custom test development capabilities for products that do not fit a standard setup. Custom fixtures help secure the item correctly, reproduce intended mounting conditions, and deliver meaningful results. This is especially valuable for complex assemblies, unusual geometries, prototype programs, and specialized industry requirements.

B83 Testing & Engineering is an ISO/IEC 17025:2017 accredited testing laboratory recognized by ANAB, the ANSI National Accreditation Board. This accreditation supports technical competence, quality management, traceability, and reliable test methods. For manufacturers, it provides added confidence that results are produced under recognized laboratory standards and can support quality, compliance, and risk-reduction objectives.
