摘要
用传统的理论或实验方法研究切削过程中各个声辐射体对总体切削噪声的贡献比较困难和繁杂.本文利用相关输入下非保守耦合系统的统计能量分析原理对薄壁圆柱壳体的切削噪声进行了研究.对于该原理所涉及的参数估计理论或测量技术以及建模等其他重要问题也进行了讨论和说明.研究结果表明,切削噪声主要产生于工件的声辐射,统计能量分析法可以成功地应用于大型圆柱壳体切削噪声的研究之中.
It is difficult to study the contribution of each sound radiator to total cutting noise in a cutting system by means of traditional theoretical or experimental methods. In this paper, problems associated with cutting noise of a cylindrical thin shell are studied by applying Statistical Energy Analysis principle for non-conservatively coupled systems under correlative excitations. Theory and techniques for parameter evaluation, cutting system modelling and other concerned important problems are discussed. Results show that cutting noise is mainly from the sound radiation of work-piece, and Statistical Energy Analysis can be applied successfully to research of cutting noise of large cylindrical shell.
