Lever-type inerter synergistic shape memory alloy self-resetting structural system
The invention provides a lever-type inerter synergistic shape memory alloy self-resetting structural system. The structural system comprises two columns, a beam, a connecting block, a level, a mass block, a rigid bracket, and self-resetting dampers. The two columns are installed at the two ends of the beam respectively to form an n-shaped frame structure. The connecting block is arranged in the middle of the beam. The top end of the lever is connected with the connecting block in a movable mode, and the connecting block moves horizontally to drive the lever to swing. The mass block is arrangedat the bottom end of the lever. The rotating fulcrum of the lever is arranged on the rigid bracket. The self-resetting dampers are mounted between the rigid bracket and the lever. According to the structural system, large inertia is provided for the structural system with small mass by utilizing the mass amplification effect of inertia, so that the effect of flexibly adjusting the natural vibration period of the structural system is achieved; and the energy consumption efficiency of the self-resetting dampers can be remarkably improved through the deformation amplification effect of the lever, and the self-resetting acting force of the self-resetting dampers on the structure is improved.
本发明提供一种杠杆式惯容增效形状记忆合金自复位结构体系，结构体系包括两个柱与一个梁，两个柱分别安装在梁的两端，以形成门字形框架结构；结构体系还包括：连接块，连接块设置在梁的中部；杠杆，杠杆的顶端与连接块活动连接，连接块水平移动以带动杠摆动；质量块，质量块设置在杠杆的底端；刚性支架，杠杆的转动支点设置于刚性支架上；自复位阻尼器，自复位阻尼器安装在刚性支架与杠杆之间。本结构体系利用惯容的质量放大作用，以较小的质量提供给结构体系较大的惯性，从而起到灵活调节结构体系自振周期的作用；而且杠杆的变形放大作用可显著提高自复位阻尼器的耗能效率，提高其对结构的自复位作用力。
