摘要提出一种新型控制装置——非对称非线性能量阱（非对称NES），以解决调谐质量阻尼器（TMD）对主体结构频率敏感和非线性能量阱（NES）对能量输入敏感的问题。非对称NES以一型NES为基础，将非线性弹簧拉离初始位置，加入线性弹簧与之平衡，所得恢复力具有线性和非线性的综合特点。在某缩尺三层钢框架结构上附加非对称NES进行试验，在脉冲型荷载作用下分析两类受控主体结构的结构响应。并使用经试验验证的数值模型，在某六层主体结构上分别附加非对称NES、TMD和一型NES进行数值研究，对比脉冲型荷载和地震作用下的结构响应。分析结果表明，非对称NES控制性能优越，兼备频率鲁棒性和能量鲁棒性，在输入能量和主体结构频率改变时均展现出良好的控制效果。

Abstract：To address current issues existing in tuned mass dampers (TMDs) and nonlinear energy sinks (NESs), a new type of mass damper, asymmetric nonlinear energy sink (Asym NES) is proposed. Asym NES is configured based on type I NES in which a linear force is introduced at a new force equilibrium position to compensate the nonlinear force, the restoring force of asymmetric NES is, therefore, a combination of linearity and nonlinearity. The Asym NES is experimentally tested on a small-scale three-story steel frame structure under impulsive excitations. The proposed device shows excellent control capacities on different structures. Using the validated numerical model, an Asym, a TMD, and an NES are numerically compared on a six-story primary structure. Structural response comparisons show that Asym NES exhibits effective control capacity in cases of various input energy and decreased structural frequency, demonstrating strong frequency-robustness and energy-robustness.

Key words： structural control nonlinear energy sink energy robustness frequency robustness numerical simulation
