Transmissibility (vibration)

Transmissibility: T = o u t p u t i n p u t {displaystyle T={frac {output}{input}}} T > 1 {displaystyle T>1} means amplification and maximum amplification occurs when forcing frequency ( f f {displaystyle f_{f}} ) and natural frequency ( f n {displaystyle f_{n}} ) of the system coincide. There is no unit designation for transmissibility, although it may sometimes be referred to as the Q factor. The transmissibility is used in calculation of passive heave compensation efficiency.
