Abstract: A gear transmission and rotation amplification type device for reducing sloshing is arranged inside and located above a body of an LNG storage tank. The device includes a combination disc, a wheel set, an outer sleeve, an overhanging fan blade, ball screws, springs and a sloshing plate. The combination disc is connected with the sloshing plate below through the springs. The combination disc is fixed above an inner wall surface of the body of the LNG storage tank, while the sloshing plate is fitted but not fixedly connected with the inner wall surface of the body of the LNG storage tank. The wheel set, the outer sleeve, the overhanging fan blade and the ball screws are arranged between the combination disc and the sloshing plate and located below the liquid level in the LNG storage tank.

Abstract: The present invention belongs to the technical fields of civil engineering, smart material and health monitoring, and provides a viscous damper fluid viscosity monitoring device and method based on piezoceramic transducers, comprising piezoceramic transducers, wires, corks, a baffle and a viscous damper. When the fluid viscosity of the viscous damper changes, the energy dissipation of pressure waves during propagation in a fluid will change, and signals received by the piezoceramic transducers will change, so that the viscosity of the fluid in the viscous damper can be calculated by the amplitude change of the signals received. The device of the present invention has a simple structure and accurate monitoring results, and provides a simple and feasible method for real-time monitoring of fluid viscosity of viscous dampers in engineering.

Abstract: A built-in spatial hammer type impact damper placed in steel tube structures is provided. A spherical mass oscillator is fixed in the center of an annular sheet housing through springs on the oscillator. Many rigid rods are fixed on the spherical mass oscillator. The annular housing, spherical mass oscillator and springs form a tuned mass damper to offset the vibration of a steel pipe structure caused by external excitation. In addition, viscoelastic energy absorbing caps are settled on the top of the rigid rods and will collide with the sheet housing when host structure vibrating. Multiple springs and rigid rods in an annular plane can reduce the level of vibration in multiple directions. Many dampers are connected through connecting rods to form a spatial hammer type damper which is placed in a circular steel pipe. Vibration reduction efficiency can be increased and the space occupied by dampers can be reduced.
