Tension-compression type magnetic shape memory alloy multi-mode intelligent damper

The invention relates to a tension-compression type magnetic shape memory alloy multi-mode intelligent damper. The damper is mainly composed of connecting flanges, a core rod, a guide nut, a cylinder barrel, magnetic shape memory units, a guide piston, a spring and a closing nut. The core rod is arranged in the cylinder barrel. The multiple magnetic shape memory units are distributed along the periphery of the core rod. The two ends of the magnetic shape memory units are connected with the guide nut and the guide piston correspondingly. The spring is installed between the guide piston and the closing nut. The connecting flanges arranged at the two ends of the damper are connected with a main body structure. The damper has multiple working states such as passive control, semi-active control and active control, is high in intelligence degree and has the advantages of high response frequency, high damping capacity, automatic resetting, stable performance and the like.
