| 摘 要： | 动力机器基础平台的动力特性不仅取决于结构材料本身的宏观弹性，而且还取决于结构平台的边界条件，地基的力学模型等参数，本文在模型实验折基础上，采用有限元法对上述问题进行了分析，确立了一种较为合理的力学模型最后给出实例。

| Abstract: | The dynamic properties of a machine-foundation platform depend not only on the quality of material of the structure, but also on the boundary conditions of the platform and the mechanical model of the foundation etc. . This paper, on the basis of the test result and the numerical analysis by FEM, gives a resonable answer to this problem. |
