摘要
把受地基约束的共用基础视为弹性体，承受不同位置大型动力机器的激振，进行基础动力特性的分析。建立了基础刚度矩阵，应用振型阻尼方法确定阻尼矩阵。
The mutual foundation being constrained by the base is regarded as an elastic body bearing severe vibration imposed by heavy power machines of large type, locating on different positions. Therein the dynamic characteristics of the base are given an analysis. A matrix to find the base′s rigid is set up, with establishment of damping matrix gained by applying vibration model damping. Herein, the reduction of vibration resulting from mutual foundation is analyzed through calculation examples, too.
