引言模态试验,与结构动力学的其他任何方面相比,大概正在经历着比较迅速的变化。随着预算开支的不断紧缩,模态试验的目的,与其他的试验科目一样,必须是经济有效的。所谓经济有效的方法是指:在技术上满足要求,最大限度消除危险,并以最少的费用完成试验。本文的目的是要讨论模态试验方法。但是,必须首先考虑模态试验结果的应用,因为这可能 Introduction Modal testing is probably experiencing relatively rapid changes compared to any other aspect of structural dynamics. As budgetary expenditures continue to tighten, the purpose of modal testing, like other pilot subjects, must be cost-effective. The so-called cost-effective method is: technically meet the requirements, to minimize the danger, and with the least cost to complete the test. The purpose of this article is to discuss modal test methods. However, the application of modal test results must first be considered as this is possible
