摘　　要：通过研究水泵机组和地基的隔振装置,建立了水泵机组的双层隔振设计模型。通过改变双层隔振系统中间质量块的质量,由仿真计算得到双层隔振系统输入功率流和传递功率流频率特性曲线等参数,并应用到实际工程中,有效地降低了噪声。结果证明,此方案是一套有效的控制措施,能完全满足国家技术标准的要求,为其他水泵机组的噪声处理提供了参考。Throngh the study of vibration isolation devices for the pump unit and foundation, the model of two - layer vibra- tion isolation of water pump unit is designed. By changing the quality of intermediate mass layer vibration isolation system, layer vibration isolation system input power flow and transmission of power flow frequency characteristics curve parameters have been got through simulation, it is applied to the actual project an can effectively reduce the noise. The results prove that this program is a set of effective control measures with excellent noise reduction effect, which can meet the requirements of national technical standards and also provide a reference for controlling other steam turbine noise.
