Element’s dynamics testing lab facilities measure and evaluate the responses of parts or systems to the dynamic forces they encounter.

Element has virtually total vibration testing capability, having multi-shaker facilities that are comprised of both electrodynamics and hydrodynamic systems.  Element provides numerous other dynamics testing including acceleration testing, shock testing, drop testing, structural and fatigue testing and rotating load simulations.

Element's Dynamics Testing Methods

Element's team of dynamics experts can tailor a solution to fit your specific needs, from vibration testing, shock testing and acceleration testing to a combined dynamic test plan. 

Vibration Testing 

Vibration testing enables you to evaluate product performance under virtually identical conditions of everyday use. Element has extensive vibration testing capabilities including multi-shaker facilities that are comprised of both electro-dynamic and servo-hydraulic systems that can reproduce low and high frequency conditions.

Shock Testing 

Shock, specifically, refers to sudden mechanical or physical acceleration or deceleration due to an impact, explosion or drop. It is measured by an accelerometer in the laboratory with engineers using vibration and shock testing to simulate transportation and service platform environments. Read more

Acceleration Testing

The stresses placed on a material or product when subjected to increasing gravity load can be catastrophic. Acceleration loads can cause structural problems such as deflection, fastener or hardware failure, and problems with flow and pressure regulation.  Element have a range of centrifuge systems to subject products to increased g loading.

Drop Testing

In the laboratory, engineers replicate real world drop and impact to simulate transportation and service platform events. Drop machines, pulse synthesis tables, and other impact equipment available at Element's product qualification testing labs readily accommodate test specimens of various sizes. Element labs also feature a 40-foot drop tower. Read more

High Cycle Fatigue 

We are specialists in High Cycle Fatigue (HCF) testing of engine air foils for service life limit analysis for our aerospace clients. Cyclic fatigue tests are digitally controlled in a closed loop servo system for safety and accuracy. Read more

Structures Testing

The complex stresses that occur during the operation of structures must be examined under static and dynamic operational loads to assess the impact of fatigue and also to determine accurate in-service life predictions. Element has the capability to design tests to mimic real world load cases utilising multiple hydraulic cylinders coupled with advanced control systems and high capacity measuring systems. Read more

Seismic Simulation

Seismic testing is designed to assess the performance of essential non-structural systems by subjecting them to strong ground shaking such as that resulting from earthquakes or nearby railways, airports, power plants and other possible causes of movement or vibrations. Read more

Engine Windmilling (Sustained Engine Imbalance)

Engine Windmilling or Sustained Engine Imbalance events occur when damage to an engine turbine occurs. This unbalances the turbine leading to large vibrations being imparted on the aircraft’s structure and flight systems. The ability to withstand these high level vibrations is safety critical. 

Testing to mimic SEI events require large displacement vibration systems which Element has available at a number of facilities across the globe. 

Spin Testing 

Rotating components like disks and blisks in aero engines are highly sensitive in terms of aircrafts' safety. A burst failure in particular (an uncontained engine failure) can result in hazardous or even catastrophic effects on the aircraft and its passengers. For this reason spin testing becomes an indispensable part of aero engine development. In Element's test facilities we are able to examine nearly every kind of rotating components of aero engines, turbine compressors, turbochargers and blowers under realistic conditions using highly sophisticated spin test rigs, with speeds up to 200,000 rpm depending on the size of the specimen. Primarily, these include disks and blisks but also other typical rotating engine components like shafts, seals, bearings, spools or impellers. Read more
