机器与柔性基础耦合系统结构噪声的控制
STUDY ON THE STRUCTUREBORNE NOISE CONTROL OF A MACHINE AND NONRIGID FOUNDATION COUPLED SYSTEM
【摘要】 针对实际工程中的复杂柔性耦合系统,从理论上探讨了由于机器上楼等引起的结构噪声控制问题.首先从结构噪声源的角度分析了结构噪声的发生机理,用此观点推导了机器-隔振器-弹性基础复杂系统的动态传递方程,并通过研究分析弹性基础的速度响应,揭示了系统各动态特性参数对结构噪声传播的影响效果,从被动与主动两方面提出了控制系统结构噪声的有效途径.
【Abstract】 The structureborne noise,which is caused by a machinenonrigidfoundation coupling system or other practical complex flexible coupling system, is studied in theory. The mechanism of the source is investigated at first, and accordingly the dynamic transfer equation of the machineisolatorflexible foundation system is deduced. The influence of the system parameters on the spread of structureborne noise is presented through the analysis on the velocity response of the flexible foundation. On these grounds, the control method both on the passive and active points is discussed.
