At present, the research on dynamics of solid-fluid interaction is generally based on the assumption that the containers are rigid which cannot meet the truth . meanwhile, there is only little research on the dynamic behaviors of the coupling system under different external excitations 目前,國(guó)內(nèi)外關(guān)于貯箱類流固耦合動(dòng)力學(xué)研究一般都建立在充液貯箱為剛性這一假設(shè)的基礎(chǔ)上,這與實(shí)際情況尚有偏頗;同時(shí),對(duì)系統(tǒng)在不同外激勵(lì)作用下的動(dòng)力學(xué)行為的研究還相當(dāng)少。
