摘要:
本文提出了一种结构动态响应算法.通过结合离散相似法和冲量定理,推演出一个计算位移和速度的递推公式.并对时序分析法作结构参数识别作了必要的分析.针对一个两自由度阻尼系统,用推得的响应公式计算该系统的位移响应,再由系统的输入输出用时序分析法识别了该系统的结构参数,识别出的参数精度较高.
Abstract:
An algorithm is presented for the dynamic responses of structures. A recurrence formula for calculating the displacement and the velocity is derived by combining the theorem of impulse with the method of discretized similarity.The analyses of parameter identification with time serieses are made.For a two-degree-freedom damped system,the displacement responses are computed by means of the formula,the structural parameters are identified with system imput and output time series,and the results are accurate.
