Abstract

The invention discloses a bidirectional TMD control device and a parameter determination method. Four steel plates are vertically arranged on a bottom plate which is horizontally disposed, a first steel plate is parallel to the bottom plate, mass blocks (6) are installed on a steel plate (19) through guide rods, and the guide rods are sleeved with vertical springs. The lower portion of a base is embedded in a rail groove of a rail assembly (12) through steel balls and steel ball clamping slots; a copper plate (9) is installed at the middle portion of the first steel plate, a left copper plate (91) and a right copper plate (9r) are installed on the portions, corresponding to the mass blocks, of the second steel plate and the third steel plate respectively, permanent magnets are installed in clamping slots, and the two ends of transversal springs (7') are connected with the fourth steel plate and the base respectively; the two ends of another pair of transversal springs (7') are connected with the fifth steel plate (5) and the base (10) respectively. The parameter determination method comprises the following steps: optimizing the TMD vertical parameter and the TMD horizontal parameter which are obtained by calculation in finite element software to obtain an optimal solution; then determining the final parameter of a TMD.

Description

technical field [0001] The invention relates to civil engineering technology, in particular to vibration reduction control technology. Background technique [0002] With the development of civil engineering, high-strength materials have been widely used in buildings and bridges, and large-span floors and stairs are also increasing. Buildings and bridges made of this material are lighter in weight. The span is larger and the natural frequency is smaller, which is closer to the walking frequency of pedestrians. This will easily cause structural resonance and produce a larger response. In severe cases, the vibration will cause buildings, bridges and other buildings (structures) to collapse and damage. In order to reduce the occurrence of accidents and the loss of life and property, the vibration control of such long-span structures is usually carried out passively, that is, to increase the structural damping, energy-absorbing vibration-reducing devices are required.
