将船上机器装置在弹性元件上是众所周知的，并且一般来说，相当有效的降噪措施。然而，系统调查限制这一措施实际有效性的因素的方法在很大程度上是不完整的。这涉及用于确定通过支撑弹性安装件以及沿沿着所谓的侧翼路径的剩余振动能量流的方法。本论文对分析船舶弹性安装系统中多路径声传递的方法以及以经济的方式改进这种系统的方法做出了新的贡献。
The installation of shipboard machinery on resilient elements is a well known and, generally speaking, quite effective noise reduction measure. However, methods for systematic investigation of the factors which limit the effectiveness of this measure in practice, are largely incomplete. This concerns methods for determining the remaining vibrational energy flow through the supporting resilient mountings and also that along so-called flanking paths. This thesis presents new contributions to the methodology for analyzing the multi-path sound transfer in resilient mounting systems on board ships and for improving such systems in an economical way.
