Relationship between the shearing rigidity of woven fabrics and fabrics ' structure parameters 梭織物剪切剛度與交織結(jié)構(gòu)的關(guān)系
In this paper , for the first time , floor stiffness is denoted as shear stiffness , which reflects the influence of floor length to width ratio more effective than floor bend - shear stiffness 本文首次把樓板的剛度用剪切剛度表示,它比樓板的彎剪剛度更能體現(xiàn)樓板長(zhǎng)寬比對(duì)樓板剛性的影響。
Abstract : based on the deformation characteristics of the tread element at typical load cases , this paper determines the displacement functions of the element by using the energy method and derives the theoretical formulae for the apparent compressive stiffness and shearing stiffness calculation 文摘:根據(jù)輪胎胎面單元在典型工況的變形特點(diǎn),用能量法確定了胎面單元變形的位移函數(shù),導(dǎo)出了輪胎胎面單元表觀壓縮剛度和表觀剪切剛度的理論計(jì)算式。
According to regress , the paper got equivalent shearing stiffness and equivalent damping gene ' s calculating formula of the hdr ' s equivalent linear model . at last , the paper estimates the effect of integrated isolation bearing with a 4 span continuous beam bridge by nonlinear dynamic analysis program 根據(jù)能量相等的原則,本論文提出了高阻尼橡膠剪切滯回曲線的雙線性模型和模型中各參數(shù)的計(jì)算公式;回歸出了用剪應(yīng)變表示的等價(jià)線性化模型的等價(jià)剪切剛度和等價(jià)阻尼比實(shí)用計(jì)算公式。
