Abstract: A tunable mass damping device, including a connecting, a weighted assembly, and a top connecting assembly connecting an upper end of the connecting rod with a tower beam of a tower and including an anti-rotation mechanism. The anti-rotation mechanism includes: a laterally extending fixing plate fixedly connected with the tower beam through a longitudinally extending supporting member; a laterally extending first movable plate arranged under the fixing plate and fixedly connected with the upper end of the connecting rod; and two connecting shafts spaced apart from each other. Each of the connecting shafts has a lower end fixedly connected to the first movable plate, and an upper end inserted into the fixing plate and connected therewith through a connecting head. The connecting head includes an intermediate elastic layer arranged between inner and outer sleeves of the connecting head.

Abstract: The spring includes an elastic member having a liquid accommodating chamber. The sealing member includes a base plate, a pressure plate, and a pressure elastic membrane provided in the liquid accommodating chamber. The pressure elastic membrane has a lip portion radially extending from an end portion of the pressure elastic membrane. The lip portion is provided with a projection. The pressure plate and the base plate define a clamping recess together. The lip portion is pressed in the clamping recess to seal the liquid accommodating chamber.

Abstract: Disclosed is a vibration-damping support device, including a housing, and a core shaft having one end passing through the housing to connect with a vibration source. The vibration-damping support device further includes two elastic members arranged within the housing and spaced apart from each other. Each elastic member includes an inner hole, so that it can be mounted on the core shaft. Each elastic member includes an elastic rubber body, and a plurality of metal plates that are embedded in the elastic rubber body and parallel to each other. The elastic rubber body extends beyond the metal plates in a radial direction. With this vibration-damping support device, a variable stiffness can be achieved.
