矩阵束方法在可控震源振动平板模态分析中的应用

摘要

This paper describes the working theory of matrix pencil in brief. The software for modal analysis is developed by LabView programming language and is applied in the modal analysis for seismic vibrator base plate. Under different modal frequencies, modal characteristics of seismic vibrator base plate are gotten, which will be very helpful for the optimization of seismic vibrator.%本文简要地介绍了矩阵束方法的基本原理，并通过LabView编程语言，开发出了基于这一方法的模态分析程序。利用这一分析程序，对可控震源振动平板进行模态分析，获得了振动平板在不同的模态频率下的模态特性，为可控震源振动平板结构的优化设计提供了指导和帮助。
