摘要
从Pall摩擦阻尼器四连杆机构的几何非线性变形特征出发,分析框架位移、支撑刚度、阻尼器摩擦力、阻尼器大小、支撑倾角、支撑屈曲力等对一种改进的Pall摩擦阻尼器—T形芯板摩擦阻尼器支撑的受力特点,拟合出可供设计人员使用的实用计算公式。
Based on the geometry nonlinearity of four-link mechanism of Pall-type frictional damper, influence of the frame displacement, brace stiffness, damper slip force, size of the damper , angle of the brace and buckling force of the braces on the maximum brace force of an improved Pall-type frictional damper(T-shaped cone plate frictional damper)is studied. And the simple practical formulae of the maximum brace force has been fitted for designer.
