摘　　要：提出了一种适用于低频动力机械的钢筋混凝土壳体基础 ,只要适当选择基础的动态参数并合理设计 ,可以使动力机械基础系统获得较好的幅频特性和明显的减振效果。使用这种基础 ,不需要任何弹性元件或减振器 ,不仅降低了成本 ,而且减振可靠。本文分析了壳体基础的减振机理和动态特性 ,给出了动力机械壳体基础的动态设计理论。A shell foundation of reinforced concrete is developed as a damper for dynamical machines with low frequency. Using this shell foundation for damping, it is unnecessary to use any other elastic components and vibration dampers, the cost to reduce the amplitude of machine foundation is much reduced and the damping is reliable. Both the damping mechanism and the dynamic analyses of the shell foundation are discussed. The results of this study show that a satisfactory amplitude frequency characteristic and obvious damping effect will be obtained if the dynamic parameters are selected properly. For dynamical machines with low frequency, the design is simple and convenient, low cost and reasonable.
