| 摘 要： | 对广义微分求积法在结构瞬态动力响应计算中的应用进行了研究，针对一维结构动力学问题，直接从控制微分方程出，提出了计算在任意激励力作用下结构动力响应的一种新方法。该方法在空间域采用ＧＤＱ法，在时间域取级数，采用时域配点的方式得到响应位移场全竞选主参数的线性代数方程组，解此方程组即可求得整个时间域的响应位移场。

| Abstract: | This paper presents the application of generalized differential quadrature method to transient structural dynamic response. It employs generalized differential quadrature method in space domain and time series in time domain. The linear algebraic equations for solving all parameters of the response displacement field are obtained by adding several time points.Numerical examples have shown the good accuracy efficiency,convenience and the great potential of this method. |
