Shock and vibration

Almost all structures are subjected to some kind of dynamic loading such as shock and or vibrations. Shock is normally of higher magnitude, resulting in direct failure, for example the pyrotechnic shock when releasing a satellite from a rocket, or the impact from dropping a piece of equipment or structure. Vibration is normally continuous loading which may lead to increased wear or fatigue.  To make sure that a product or structure is designed to cope with the expected dynamic loading it can be simulated dynamically in the time domain or harmonically in the frequency domain.

We have long experience working with shock and vibrations, also with submerged structures including the effect of added mass of the surrounding water. Withing the field of underwater dynamics, Lightness have contributed to research and publications within the field.
