介绍了变曲率摩擦摆隔震支座的特点，分析了不同参数对变曲率滑动曲面的影响。将某球面摩擦摆隔震支座改进设计为变曲率滑动曲面的摩擦摆支座，并利用有限元软件ABAQUS对隔震支座进行实体单元建模。对比了不同曲率变化程度的变曲率摩擦摆支座和球面摩擦摆支座在低周反复荷载作用下的滞回性能。数值分析结果表明：变曲率摩擦摆隔震支座的滞回曲线饱满，具有良好的滞回耗能能力，且其滞回耗能能力优于球面摩擦摆支座；当滑动曲面方程选择合适时，该支座的耗能能力可达到最佳。

The characteristics of friction pendulum bearings with variable curvatures was introduced . Effects of different parameters on sliding surface with variable curvature were analyzed .Then a spherical friction pendulum bearing was designed to bearings with variable curvatures .And solid element modeling of isolation bearings were built using the finite element software ABAQUS .Comparison of hysteretic behaviors under low cy-clic loading was conducted between friction pendulum bearingswith variable curvatures and that of spherical sur -face.The numerical results show that bearings with variable curvatures have good hysteretic energy dissipation capacity with full hysteresis curves .And the capacity is better than that of bearings with spherical surface .When an appropriate equation of sliding surface is selected , the bearings can achieve optimal energy dissipation capacity .
