[提要] 根據(jù)對火力發(fā)電廠大型輔機(jī)基礎(chǔ)的動(dòng)力特性測試與理論計(jì)算結(jié)果，分析了構(gòu)架式（高、變轉(zhuǎn)速設(shè)備基礎(chǔ)）、彈簧減振式、大塊式、放置在樓蓋上的設(shè)備等不同形式基礎(chǔ)的動(dòng)力特性，并提出了有關(guān)動(dòng)力基礎(chǔ)設(shè)計(jì)和計(jì)算方法的一些新建議。還介紹了以通用微機(jī)為核心的SVMA模態(tài)分析系統(tǒng)。應(yīng)用此系統(tǒng)對大量實(shí)測數(shù)據(jù)進(jìn)行分析處理，得到了滿意的結(jié)果。
[關(guān)鍵詞] 輔機(jī)基礎(chǔ) 動(dòng)力測試 模態(tài)分析It's analyzed that the dynamic feature of frame-type foundation (high rotational speed and changeable rotational speed), spring-type foundation, biock foundation and the equipment foundation on the floor are basis on testing results and theory caiculations. Some new suggestions are also given on the rotational equipment foundation design and calculation method. SVMA module analysis system on PG computer is introduced. The testing data of this paper are analyzed with this system.
Keywords: auxilary equipment foundation; dynamic measuring; module analysis
