多点激励模态分析技术的形式和内容

本文以多点激励下模态分析技术的理论和应用为主题,以作者对这一新兴技术概念的理解和实践为基础,通过对多点激励技术概念和方法的历史回顾和归纳,比较全面地对该技术中的各种具有代表性方法的实际作用和地位进行了评述。文章把多点激励技术看成一个整体,综合论述了影响其模态分析精度的各种内在因素,并提出了提高参数识别精度的相应方法。

THE FORM AND CONTENT OF MULTI-EXCITATION MODAL ANALYSIS TECHNIQUES

The uses and positions of MET are discussed with the substance of the theories and applications of Multi-Excitation Modal Analysis. Techniques. by means of reviewing the development of the technique and generalizing its concept. The concrete practice and understating from the- author about the new technique are reflected, and MET arid identificant alogorithms are regarded as a whole that can't be separated. In the light of the view point, many factors that cause errors are presented. Finally ,corresponding methods improving the precision of the parameter identificator are put forward.
