Embodiment Construction

[0024] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0025] combine figure 1 ~7. The present invention relates to a composite shape memory alloy damper composed of a core energy dissipation element 1, an upper connecting steel plate 2, a lower connecting steel plate 3, a shape memory alloy wire bundle 4, a steel column with holes 5, and a clamp 6. The upper connecting steel plate 2 and The core energy-dissipating element 1 is fixed in the middle of the lower connecting steel plate 3, and the core energy-dissipating element 1 is a rubber vibration isolation pad. Four perforated steel columns are respectively fixed on the four vertices of the upper connecting steel plate 2 and the midpoints of the four sides of the lower connecting steel plate 3, four groups The shape memory alloy wire bundle 4 passes through the perforated steel column 5 and wraps around the core energy-dissipating element 1 , and the two ends are ti...

Abstract

The invention aims to provide a composite shape memory alloy damper comprising an upper connecting steel plate, a lower connecting steel plate, a core energy-dissipating element, upper perforated steel columns, and lower perforated steel columns. The core energy-dissipating element is fixed between the upper connecting steel plate and the lower connecting steel plate. The upper and lower connecting steel plates have same edges. The upper perforated steel columns are mounted at vertexes of the upper connecting steel plate. The lower perforated steel columns are mounted at midpoints of the edges of the lower connecting steel plate. Both the upper and lower perforated steel columns are arranged between the upper and lower connecting steel plates. Each two adjacent upper perforated steel columns and the lower perforated steel column between the upper perforated steel columns are connected through a shape memory alloy strand penetrating pores in the upper and lower perforated steel columns; fixtures are mounted at two ends of each shape memory alloy strand; the shape memory alloy strands are fixed to the upper perforated steel columns through the fixtures. The composite shape memory alloy damper has the advantages that vertical drawing resistance can be improved, fewer parts are used, mechanical strength is high and stability is good.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular a damper. Background technique [0002] In recent years, due to the development of industry and the needs of production, new requirements have been put forward for the precision and use environment of equipment, especially in the fields of aerospace, ships and other high-precision defense. In modern technology research, vibration is basically studied and controlled as a harmful aspect. On the one hand, mechanical equipment always inevitably has natural vibration or forced vibration during use. On the other hand, the existence of vibration always affects the normal operation of various precision instruments and meters, and also causes environmental noise pollution. Therefore, the control of vibration is particularly important. [0003] As the most commonly used material in the field of vibration reduction, rubber material is one of the more mature materials studied so far. However, it h...
