摘要: 直接从控制微分方程出发,以梁为对象提出了本计算方法。该方法在空间域采用DQ法(DiferentialQuadratureMethod),在时间域取级数,采用时域配点的方式得到求位移场全部待定参数的可解方程组,求解一次线性方程组即可求得全域的响应位移场。

关键词: 半解析法, 动力响应, DQ法

Abstract: A method is proposed for controlling partial differential equation directly to beam.It takes differential quadrature method in space domain and series in time domain,and yields equations of determining all parameters for the displacement field by adding time points.The response displacement field can be obtained by solving linear equations.

Key words: semianalytical method, dynamic response, differential quadrature method
