Axial variable stiffness friction damper
The invention relates to the technical field of seismic reduction and isolation equipment, in particular to an axial variable stiffness friction damper. The damper comprises a plurality of pressing plates and a plurality of friction steel plates, wherein each friction steel plate is clamped between two corresponding pressing plates; strip-shaped friction materials capable of generating friction force are arranged on the contact faces between the friction steel plates and the pressing plates, and variable cross-section structures capable of enabling friction loads to be increased along with increase of displacement are arranged on the friction steel plates and the friction materials; and the variable cross-section structures comprise first variable cross-sections arranged in the middles ofplate bodies of the friction steel plates and second variable cross-sections arranged on the friction materials, and the cross-section angle theta of each variable cross-section can be changed. Aimingat the defects in the prior art, the invention provides the axial variable stiffness friction damper with reliable performance, and the friction force can be increased along with the displacement change, so that the energy consumption capacity is improved, and the seismic reduction efficiency is better.
本发明专利涉及减隔震设备技术领域，具体涉及一种轴向型变刚度摩擦阻尼器。该阻尼器包括若干块压板和摩擦钢板，各摩擦钢板均夹在两块压板之间，摩擦钢板与压板的接触面上均设置有能产生摩擦力的条形摩擦材料，摩擦钢板和摩擦材料上均设置有能够使摩擦载荷随位移增大而增大的变截面结构。变截面结构包括设置在摩擦钢板板身中部的第一变截面和摩擦材料上的第二变截面，各变截面的截面角度θ均能够改变。本发明针对现有技术的不足，提供一种性能可靠的轴向型变刚度摩擦阻尼器，摩擦力能够随位移变化而增大，从而提高耗能能力，减震效率较好。
