Abstract: A friction lining assembly having a backing plate and a sheet metal restoring spring fixed thereto, for a partially lined sliding-caliper type disk brake having a brake holder fixed with respect to the vehicle, on which friction lining assemblies arranged on both sides of a brake disk are slidably guided. A housing, which extends over the brake disk and the friction lining assemblies, is slidably mounted on the brake holder.

Abstract: An active tuned mass damper applied to the offshore monopile wind turbine belongs to the field of marine technology. A mass block is connected to the inner wall of the tower through a spring. The two ends of the damper and the force actuator are connected to the mass block and the inner wall of the tower, respectively. When the installation of tower is finished, the spring and the damper begin to work. The movement of mass block will partly offset the movement of the tower caused by the wave force. The force actuator starts to work before the mating. The exact position of the nacelle can be obtained from the Global Positioning System (DGPS). The position of tower can be adjusted in the horizontal plane through the force actuator. So, the offshore installation time for nacelle will be saved. The whole installation time and cost will also be reduced.
