Abstract: The present invention belongs to the field of monitoring technology and signal analysis of lattice tower structures, and discloses a horizontal two-dimensional displacement reconstruction method for a lattice tower structure based on multi-source heterogeneous data fusion. a lattice tower is simplified into a thin-walled three-dimensional variable section cantilever beam, a two-dimensional strain-displacement mapping method is used to calculate the horizontal two-dimensional displacement with low sampling rate, and finally a multi-rate Kalman filter algorithm is used to fuse the displacement with horizontal two-dimensional acceleration to obtain the horizontal two-dimensional displacement with high sampling rate. A data fusion method of the present invention needs less sensors, is simple in calculation process and accurate in calculation results, and has strong operability and practicability.

Abstract: The present invention belongs to the technical field of energy consumption and vibration reduction of assembled building structures, and provides an energy-consuming connecting device for a prefabricated assembled wall. The present invention provides a normal connection function between walls, and also has the functions of energy consumption and vibration reduction. A used viscoelastic material can provide energy consumption and weaken the cold and hot bridge effect, which is beneficial to building thermal insulation. Meanwhile, the energy-consuming connecting device for the prefabricated assembled wall can be connected with a prefabricated wall in advance, which can be carried out at the same time as the wall is inserted during construction, thereby effectively increasing the construction efficiency. Through the design of clamping groove devices, the wall can be connected firmly and reliably while generating displacement and consuming energy. A multi-segment fixing plate is used to replace full-length arrangement to save the steel.

Abstract: An eddy current energy-dissipating spacer is mainly composed of a spacer frame, a conductor clamp and energy-dissipating elements. The eddy current energy-dissipating spacer not only provides the function of an ordinary spacer, but also reduces the vibration of the transmission lines; and at the same time, can effectively reduce the vibration of the transmission lines, especially the torsional vibration by adopting the eddy current and viscoelastic material for energy dissipation; improves the eddy current strength by adjusting the gear radius ratio, thus increasing the damping force; can adjust the damping parameters by adjusting the magnetic field strength of the permanent magnet; can produce long-term stable vibration reduction effect by adopting the permanent magnet to provide continuous magnetic field without additional external energy input; can effectively avoid the magnetic flux leakage of magnetic circuits by adopting the magnetic material.
