    摘要: An external cargo damping system includes lifting gear and a damping assembly. The lifting gear has a lifting body attachment end and an opposed external cargo end, and defines a load path that extends between the lifting body attachment and external cargo ends of the lifting gear. The damping assembly is connected in series with the lifting gear and is disposed along the load path to damp vibratory force transmitted between the lifting gear lifting body attachment and lifting gear ends.

    摘要: A hydraulic system (600) and method for reducing boom dynamics of a boom (30), while providing counter-balance valve protection, includes a hydraulic actuator (110), first and second counter-balance valves (300, 400), first and second control valves (700, 800), and first and second blocking valves (350, 450). A net load (90) is supported by a first chamber (116, 118) of the hydraulic actuator, and a second chamber (118, 116) of the hydraulic actuator may receive fluctuating hydraulic fluid flow from the second control valve to produce a vibratory response (950) that counters environmental vibrations (960) on the boom. The first blocking valve prevents the fluctuating hydraulic fluid flow from opening the first counter-balance valve. The first blocking valve may drain leakage from the first counter-balance valve.

    摘要: Two or more front-side vibration suppression force generation sources and two or more rear-side vibration suppression force generation sources are interposed between bogies and the vehicle body. A controller calculates a sway high-frequency vibration suppression force for suppressing vibration having a frequency which is not less than a frequency of a centrifugal acceleration acting on the vehicle body when the railway vehicle runs in a curve section. The controller lets at least a part of the front-side vibration suppression force generation sources and at least a part of the rear-side vibration suppression force generation sources output a resultant force of a yaw suppression force and the sway high-frequency vibration suppression force. The controller lets all the remaining vibration suppression force generation sources function as passive dampers when the railway vehicle runs in the curve section. Ride quality of the vehicle in the curve section is thereby improved.
