The effect of the Coriolis acceleration component on the forced response is illustrated by comparing the results for a travelling force on a stationary ring with results for a rotating ring subjected to a stationary force.
This is accomplished by placing force exciters along a structure spatial array, spaced a distance ΔX apart, and each force exciter is activated for a short period of time to simulate a travelling force traversing the structure forwards and backwards.
