摘要
针对实际工程中柔性基础上机器所产生的结构噪声问题 ,从结构噪声源的角度出发 ,分析了结构噪声的控制问题 本文按照机械阻抗的观点 ,用传递导纳矩阵法推导了机器、隔振器和弹性板基础复杂柔性耦合系统的动态传递方程 ,着重研究了板基础的速度响应 。
The structural noise, which is caused by a machine on the flexible foundation in practical engineering, is studied from the point of view of the structural noise source The dynamic transfer equations of the complex flexible coupling system composed of the machine, isolators and elastic plate-like foundation are deduced according to the mechanical impedance method The velocity response of the plate foundation is studied in detail The effect of parameters of the system on the structural noise is analyzed
