| 摘 要： | 本文研制了在IBM—PC及其兼客机上实现的模态分析商品化软件。该软件可以对单点激振,多点拾振所获得的若干组频响函数同时拟合,从而获得系统的模态参数。利用该软件对一块悬臂钢板所作的模态参数识别结果表明,该软件识别精度高,商品化程度强。

| Abstract: | This paper introduced a piece of practical software to IBM/PC(/XT/AT).To this software we applied algorithm of global estimation of modal frequency and damping ratios from a set of frequency response functions(FRF)measured.Finally,a practicable exam- ple was obtained.From this it could be found that this software was practicable and satisfac- tory. |
