Shock & Vibration Testing
Critical shock and vibration can occur at relatively low frequencies, such as with automotive shock and vibration testing, or at higher frequencies such as Aerospace applications.
TRaC have a range of vibration testing equipment that can reproduce low and high frequency conditions. These vibration testing conditions are representative of in service applications, on products as small as a microswitch and as large as a train carriage. A range of electro-mechanical and electro-hydraulic vibration testing systems are used, with standard test frames, to apply dynamic vibration test loads suited to any requirement.
Mechanical shock testing replicates events that are encountered regularly during the day to day operation of equipment or products. Shocks can be generated in day to day general handling or shocks by in service applications such as underwater explosions or high speed motion in extreme cases. Shocks are generally characterised by their short duration and sudden occurrence.
TRaC has a range of capabilities with regard to shock testing. Using a choice of vertical-drop shock test machines or electromagnetic shakers, a variety of shock profiles, pulse durations and shock levels can also be achieved. TRaC can also characterise the shock levels of a product using shock response spectrums (SRS). Again, shock testing is a dynamic parameter used to represent the in service life of components.
TRaC provides the following shock and vibration testing services
Shock and Vibration Testing Fixtures
To ensure that dynamic forces are applied to components in a way which is representative of their in-service conditions, a bespoke rig or fixture may have to be used. TRaC has the capability and engineering expertise to both design and manufacture such a rig or fixture as necessary to read more click here.
