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,國內(nèi)外關(guān)于貯箱類流固耦合動力學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,這與實際情況尚有偏頗;同時,對系統(tǒng)在不同外激勵作用下的動力學行為的研究還相當少。
