|
摘要
基于大量SMA耗能阻尼器力学试验,根据阻尼器工作时刚度渐变的特点,提出了连续刚度力学模型,建立了SMA耗能阻尼器性能参数的简易计算公式,给出了相关参数的计算方法并分析了对SMA耗能阻尼器性能参数计算结果的影响。试验分析结果表明:1)连续刚度力学模型滞回曲线与试验滞回曲线相吻合,适用于SMA耗能阻尼器的力学研究;2)应用SMA耗能阻尼器性能参数简易公式计算的阻尼器性能参数值与试验值的误差小于7%。
Based on a large number of SMA damper mechanical testing,according to characteristics of stiffness that was changed gradually when a damper was run,the mechanical model of continuous stiffness was proposed and the simple formula for performance parameters of SMA damper was established,the calculation method of the parameters was given,and the influence on the result of the performance parameters was analyzed.The result of the test analysis showed: 1) hysteresis curve of the continuous stiffness mechanical model corresponds to the test hysteresis curve of SMA damper mechanics;2) the error between the simple formula value and the test value is less than 7%.
