## Random Vibration Analysis – Nastran SOL 111

Introduction Random vibration is motion which is non-deterministic, meaning that future behavior cannot be precisely predicted, and it is a characteristic of the input or excitation. To specific a random vibration is usually is used the ASD (acceleration spectral density). … Continue reading

## Vibration Analysis – Nastran SOL 103

General Overview There are many reasons to compute the natural frequencies and mode shapes of a structure. One reason is to assess the dynamic interaction between a component and its supporting structure. For example for those parts nearby … Continue reading
