一、前言随着近代工业的发展,振动和噪音污染日趋严重,同时,振动也降低机械、仪器的使用性能和寿命。因此,如何减小机械振动,降低噪音已成为工程技术领域内一项重要任务。传统的机械和结构系统减振降噪方 I. Introduction With the development of modern industry, vibration and noise pollution are becoming more serious. At the same time, vibration also reduces the serviceability and life span of machinery and instruments. Therefore, how to reduce mechanical vibration and reduce noise has become an important task in the field of engineering technology. Traditional mechanical and structural systems vibration and noise reduction side
