A floor assembly includes a controller, a compressor, an airbag, and a floor. The controller is configured to provide one or more user controls to permit a user to operate the compressor and regulate pressure in the airbags. The floating floor is configured to isolate a carrying load from vibrational effects and trailer forces. The assembly is optionally removable from a trailer floor and may be inserted on a different trailer. A guide member is used to restrict movement of the floor on the airbags to only a vertical motion. The guide members may include a dampener.

A parameter setting method includes a parameter value changing step of, when the magnitude of a deviation that is a difference between a command position and an actual position of a movable portion is greater than or equal to a prescribed value during operation of an active damper, selecting an unselected set of candidate values from among a plurality of sets of candidate values and changing the values of respective types of parameters of the active damper to the selected set of candidate values, and when the magnitude of the deviation is less than the prescribed value, not changing the values of the respective types of the parameters. After the parameter value changing step is finished, the parameter value changing step is repeated until the magnitude of the deviation becomes less than the prescribed value.

A hybrid damping module, a vibration suppression device, a vibration suppression method and a wind turbine set. The hybrid damping module comprises a first damping unit (8). The first damping unit (8) comprises a rotor portion (8a) and a stator portion (8b) that is provided parallel to the rotor portion (8a). The rotor portion (8a) is configured to capable of rotating relative to the stator portion (8b) so as to generate electromagnetic damping. A flow passage is formed in at least one of the rotor portion (8a) and the stator portion (8b). The hybrid damping module comprises a second damping unit (10) comprising a liquid damper. The liquid damper communicates with the flow passage and forms a circulation loop. A liquid (10p) in the liquid damper can cyclically flow in the circulation loop. In the hybrid damping module, a combined vibration suppression solution that combines a TMD and TLD is provided.
