Hello Peter, Can you help me with this please?

I want to apply a base excitation displacement that represents the engine vibration in a machinery room. The engine power is 3070 HP at 1050 rpm, and the analysis will be done in this range of frecuencies: 14 - 34 Hz. 

I saw this reply, do you have any source that establishes what is the amplitude of base displacement adequate for a frecuency?
