文章提出了一种U型软钢阻尼器,并根据该阻尼器的受力特点,建立了相应的力学分析模型。同时,运用ANSYS有限元软件模拟了该阻尼器的滞回特性,获得了其主要力学性能参数,并与所建立的力学分析模型进行了对比分析,二者基本一致。从分析结果可以看出,本文所设计的U型软钢阻尼器具有良好的受力性能和理想的滞回耗能特性。

This paper supposes a U-shape low yield steel damper.Based on the mechanical behaviors of the damper,its analytical model is established.Meanwhile,the damper＇s hysteretic characteristics are numerically simulated by the FEM ANSYS to obtain the main mechanical parameters of this damper.These parameters are compared with the results from the established analytical model.Results indicate that the analytical model is agreeable to the FEM analysis.In addition,Analytical results also show that the U-shape low yield damper possesses superior mechanical behaviors and hysteretic characteristics to fit extremely for mitigating the vibration of engineering structures.
