Shape memory alloy plate self-resetting friction damper and method
The shape memory alloy plate self-resetting friction damper comprises a fixed friction block, the fixed friction block comprises an upper side fixed friction block and a lower side fixed friction block, and the upper side fixed friction block and the lower side fixed friction block are oppositely arranged; a shape memory alloy plate is arranged in the center between the upper fixed friction block and the lower fixed friction block, one side of the shape memory alloy plate is connected with a left connecting steel plate, the other side of the shape memory alloy plate is connected with a right connecting steel plate, a left sliding friction block is arranged in the middle of the left connecting steel plate, and a right sliding friction block is arranged in the middle of the right connecting steel plate. And the shape memory alloy plate is not in contact with the upper side fixed friction block and the lower side fixed friction block. After all the components are installed, the damper is pre-stretched, pre-tightening force is applied to the position where the friction block is fixed, so that it is guaranteed that the internal stress of the damper is balanced before the damper resists external force, when the external force is increased, friction force is reversed and jointly resists the external force with the shape memory alloy, and high anti-seismic and self-resetting capacity is provided.
一种形状记忆合金板材自复位摩擦阻尼器及方法，包括固定摩擦块，固定摩擦块上包括上侧固定摩擦块与下侧固定摩擦块，上侧固定摩擦块与下侧固定摩擦块相对设置，位于上侧固定摩擦块与下侧固定摩擦块之间的中心位置布置有形状记忆合金板材，形状记忆合金板材一侧与左侧连接钢板相连，另一侧连接右侧连接钢板，左侧连接钢板中间布置左侧滑动摩擦块，右侧连接钢板中间布置右侧滑动摩擦块，形状记忆合金板材不与上侧固定摩擦块与下侧固定摩擦块接触。在安装好各个部件后对阻尼器先进行预拉伸，并在固定摩擦块处施加预紧力，以保证阻尼器在抵抗外力前内部的受力平衡，当外力增加时，摩擦力反向与形状记忆合金共同抵抗外力，提供较强的抗震、自复位能力。
