摘要
本文研究了一种新型软钢阻尼器。首先分析了这种阻尼器的力学性能和减震机理,依据试验结果给出了它的恢复力模型,并推导得出了特征参数的表达式和疲劳验算式;研究了阻尼器参数对减震效果的影响,给出了最佳的参数取值范围;算例分析表明该种阻尼器具有很好的减震效果。
This paper presents the research result on the mechanism and parameters analysis of a new type of mild steel damper developed by IEM. Based on quasi-static test data, the hysteretic model is derived and the fatigue model is set up according to fatigue test. The optimal reslationship between damper papameters and effectiveness is determined through parameter study. Numerical simulation results show that this damper is quite effective.
