A semi-analytic method is proposed for solving dynamics initial-boundary value problems of one dimension under alternate force.It adopts differential quadrature method in space domain and series in time domain on the basis of controling partial differential equation,and gets DQ linear equations for solving all parameters of the displacement-field by adding timepoints.
