| 摘 要： | 弹性地基上梁的振动问题求解一直受到工程界的广泛关注。本文应用广义微分求积法(GDQ)对弹性地基上梁进行动力分析，求出其前5阶固有频率，并与用微分求积单元法(DQEM)和有限元法(FEM)的计算结果进行对比，结果表明GDQ计算工作量小而精度高。

| Abstract: | In engineering fields, it is well known that vibration analysis of beam on elastic foundation is a very important problem. In this paper, the former five frequencies of beam on elastic foundation have been obtained by generalized differential quadrature method (GDQ) and are compared with numerical results by DQEM and FEM. It is shown that GDQ is a good method to deal with vibration problems of beams on elastic foundation. |
