    effect of mass on vibration response

    Thanks guys - I'm using Mil-Std-810 to give my input PSD (and peaks due to rotor and BPF) - it just seems logical to me that the bigger mass would have a lower output g level, I'm just not sure how to quantify it !

    effect of mass on vibration response

    Do you mean because of mass damping effects ?

    effect of mass on vibration response

    If I have 2 installations on a helicopter floor, similar natural frequencies but 1 weighs 5 kg the other 500 kg, would the response of each to the same random vibration input (PSD) be the same ??
