Simulation of shock and vibration tests
Many structures and instruments attached to different vehicles need to fulfil certain shock or vibration requirements. In most cases this has to be proved using physical shock or vibration testing according to some specific standard.
Fulfilling these requirements is often difficult and time consuming and several product development iterations are needed. Specially, a vibration fatigue assessment is very time consuming using traditional product development tools.
At Stressfield, we have simulated short duration shock test as well as long duration vibration tests for equipment in ships and railway applications. Simulations have provided good results in relatively short time. Results were confirmed afterwards using physical testing according to applicable standard.
