Transmissibility (structural dynamics)

Template:Template otherTemplate:Expand Arabic Transmissibility, in the context of structural dynamics, can be defined as the ratio of the maximum force ($f_{max}$) on the floor as a result of the vibration of a machine to the maximum machine force ($P_0$):

$TR=\frac{f_{max}}{P_0}=R_d\sqrt{1+(2\zeta \beta {)}^2}$

Where $\zeta$ is equal to the damping ratio and $\beta$ is equal to the frequency ratio. $R_d$ is the ratio of the dynamic to static amplitude.
