Short summary
The approximate calculation of a Stockbridge type damper's natural frequencies and its sensitivity were studied. The low-order frequency is highly sensitive to the cable's length, moderately sensitive to the damper's mass, and slightly sensitive to the eccentric distance and the damper's gyration radius. The high-order frequency is highly sensitive to the cable's length and the damper's gyration radius, moderately sensitive to the damper's mass, and slightly sensitive to the eccentric distance.
