Structure-borne noise control and optimum design for a resilient compound vibration system

  • 摘要: 本文研究了复杂线性振动系统的结构噪声控制问题,着重分析了设备弹性与振源输出特性对系统结构噪声抑制效果的影响,从理论上对高频隔振进行了深入探讨,给出了考虑设备与基础阻抗时复杂线性弹性系统的力传递率;建立了同时带频率及结构装配关系约束的优化设计数学模型,并就所关心的频段进行了优化分析。

     

    Abstract: It is discussed in detail to control the structure-borne noise of a linear resilient compound vibration system in this paper.The influnce of both the equipment resilience and the export characteristic of vibration sources to the effectiveness of structure-home noise reduction is analysed emphantically.The force transmissibility of the compound vibration isolation system is derived when both the equipment and the foundation are resilient.The optimum mathematical model of this system is founded and the optimum analysis is made on an interesting frequency region when a frequency restrain and assembly relation restrain are considered simultaneously.
