    摘要: A shock absorbing device may include a housing, a piston, and membrane. The housing may define space. The piston may move within the space to adjust a pressure of a gas in a main spring chamber to form a gas spring. The piston and the housing may partially define the main spring chamber within the space. The membrane may be positioned in the space. The housing and the membrane may define a secondary spring chamber within the space. The membrane may partially define the main spring chamber and may be sufficiently elastic such that when the piston adjusts the pressure of the gas in the main spring chamber, a force applied on the membrane by the gas in the main spring chamber changes and causes the membrane to selectively deform to adjust a pressure of gas in the secondary spring chamber to control a spring rate of the gas spring.

    摘要: A supporting device including an installation assembly; a first supporting arm assembly having a longitudinal direction, a first end, and a second end; a switching bracket; a bearing unit pivotally connected to the switching bracket; and at least one gas spring is provided. The first end is pivotally connected to the installation assembly. The switching bracket is pivotally connected to the second end of the first supporting arm assembly. The gas spring is disposed in the first supporting arm assembly and is respectively connected to the switching bracket and the installation assembly to provide a supporting force. Each gas spring has a hollow tube, a piston rod, and a compression spring. The piston rod is slidably disposed through the hollow tube and has a head. The head may be varied between maximum and minimum protruding positions relative to the hollow tube. The compression spring is sleeved on the piston rod.

    摘要: A method of assembling a tower section of a wind turbine tower is provided. The method includes arranging the tower section of the wind turbine tower in a horizontal orientation; transporting a damper unit to a position inside the tower section while the tower section is arranged in the horizontal orientation; and mounting the damper unit to the tower section, wherein the damper unit is configured to damp motions of the wind turbine tower. Further, a horizontal transport system is provided that is supported at least at one position by the tower section and that includes a movable part configured to support a damper unit and to transport the damper unit in a horizontal direction from a position adjacent to an end of the tower section to a position at or adjacent to a mounting position of the damper unit inside the tower section.

    摘要: A large-cooling-capacity integrated Stirling pneumatic refrigerator supported by large-stroke column springs, consisting of an active vibration absorber, a motor, a coaxial type compression-expansion piston, a compression piston column spring, an expansion piston column spring, a hot-end radiator, a cylinder wall, a housing, and a cold finger, wherein the coaxial compression-expansion piston is composed of a compression piston and an expansion piston, the expansion piston is nested in the compression piston, and the compression piston and the expansion piston share one hot-end radiator; the compression piston is driven by a motor, and the expansion piston is driven by gas force and no motor drive is required. The compression piston and the expansion piston are both supported by column springs, the column spring provides an axial restoring force for the coaxial type compression-expansion piston. The active vibration absorber is installed at the tail part of the housing.

    摘要: An enclosure with a vortex-induced vibration suppression function and a method for suppressing vortex-induced vibration are provided. The enclosure is provided with suction through holes extending through a peripheral wall thereof, the suction through holes are distributed in a circumferential direction of the enclosure. The enclosure is further provided with a suction apparatus, and the suction apparatus can perform suctioning to the suction through holes from outside to inside, to restrain a boundary layer at an outer surface of the enclosure from being detached from the outer surface. By the suctioning, the boundary layer can be “adsorbed” on the outer surface of the tower, thereby restraining or directly preventing the boundary layer from being detached from the outer surface of the tower, and reducing or eliminating the cause of the vertex-induced vibration.
