Abstract: A wind field interpolation simulation method based on isogeometric sampling, the main steps of generating a wind speed time series in the present invention are as follows: first, inputting basic parameters of wind field simulation and the number of initial sampling points, and selecting the sampling points by an isogeometric sampling method. Then calculating the maximum relative error of all frequency bands by a relative error defined, and judging a fitting error and an allowable error given. If the fitting error is greater than the allowable error, increasing the number of sampling points and reselecting the sampling points; if the fitting error is less than or equal to the allowable error, finishing point selection, and using an interpolation function to calculate a lower triangular matrix required by the simulation. Thus a fluctuating wind field can be generated by a harmonic superposition method.

Abstract: An axial displacement amplified eddy current damper is disclosed. The axial movement of a slide bar is converted into the rotation of copper sheets and generates eddy current for energy consumption. The copper sheets are rotated and amplified by adjusting the sizes of gears. The short displacement of the slide bar can cause a large angle rotation of the copper sheets, so that energy consumption efficiency is high. The damping parameter can be adjusted by adjusting the magnetic field strength of permanent magnets, the thickness of the copper sheets and the distance from the copper sheets to the permanent magnets. The permanent magnets are adopted to provide continuous magnetic field sources, without external energy, thereby generating long-term and stable vibration reduction effect.

The coupling beam eddy current damper with shear displacement amplification comprises a rigid rod, rotating shafts, a pin column, pins, levers, screws, thread sleeves, copper sheets, permanent magnet components, a steel structural component, balls, ball supports and an outer shell. When vibration occurs, coupling beams on both sides of the damper are relatively vertically displaced; at this moment, two levers move up and down relative to the rigid rod; the movement causes the screws and the copper sheets to rotate; the copper sheets rotate in a magnetic field, then induced electromotive force will generates inside the magnetic field, thereby generating eddy current in the copper sheets. The eddy current effect will produce a damping force that impedes the rotation of the copper sheets.
