| Abstract: |
| The boundary integral method is used to study the forced vibration of thick rectangular plates under three complex boundary conditions,namely,simply supported on four sides,fixed two opposite sides and simply supported on two opposite sides,and fixed on four sides.The solution process is clear,and the governing equations of forced vibration and the equations of the flexural surface are given.Through numerical calculation on the Matlab platform,the calculation results in the form of charts are obtained,and compared with the finite element simulation results.From the comparison of these results the accuracy of applying the boundary integral method to solve the forced vibration problem of thick rectangular plates and the correctness of the derived governing equations and the flexural surface equations can be seen.It has certain practical significance for various related problems in engineering practice,and provides a new way for solving such problems,which can be directly applied to engineering practice. |
