Recently, according to the enlargement of rotating equipment such as turbines and pumps, the dynamic characteristics of bearings and seals tends to greatly affect the dynamic characteristics of the rotor system. Therefore, numerous researchers have been engaging in developing the hydrodynamically lubricated bearing theory and seal theory. However, it is still difficult to estimate the precise dynamic characteristics of bearings and seals analytically. On the other hand, there are many researcher who have been developing the experimental measurement technique of bearing and seal dynamic characteristics. This paper describes the measurement technique of bearing and seal dynamic characteristics using the random excitation technique.
