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,本文在模型实验的基础上,来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。
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.
