The expressions of the maximum deflection were derived through mechanics analysis , and the parameters affecting the maximum deflection were discussed 根據(jù)力學(xué)求解最大撓度的表達(dá)式,并討論影響最大撓度的因素以及在實(shí)際(特別是纖維的燒結(jié)和拉伸環(huán)節(jié))中的應(yīng)用。
The analysis indicates that the maximum deflection is directly proportional to density and the square of span , and inversely proportional to stress , but independent of diameter and elastic modulus 分析結(jié)果表明:由于絲線長(zhǎng)徑比很大,絲線的最大撓度跟密度以及跨度的平方成正比,與所受的應(yīng)力成反比,而同絲線的直徑的具體數(shù)值和材料的剛度無(wú)關(guān)。
Study of practical formula about strength and rigidity of 6 - point - supported - glass using the super sap fea software to solve different calculation models - which have different parameters , such as a / b , a / c and so on , this paper achieves a series maximum deflection coefficients and maximum stress coefficients , then form calculation formulas of maximum deflection and maximum stress under the load of wind 6點(diǎn)支承玻璃強(qiáng)度剛度實(shí)用的計(jì)算公式研究采用supersap有限元分析,求出不同的計(jì)算模型(玻璃板的尺寸參量a b , a c不同) ,得出一系列最大撓度系數(shù)和最大應(yīng)力系數(shù),形成6點(diǎn)支承玻璃在風(fēng)載荷作用下的最大撓度計(jì)算公式和最大應(yīng)力的計(jì)算公式。
The vehicle load is simplified as static load . the influence of asphalt concrete temperature , the resilient modulus of the semi - rigid base and the composite foundation on the maximum deflection of the road surface , retained deflections , the radial stress of the base bottom and sub - base bottom is discussed . the working properties are analyzed by fem based on elasto - plastic dynamic mechanics 第三,采用drucker - prager屈服準(zhǔn)則模擬復(fù)合地基和軟土地基,將車輛荷載簡(jiǎn)化為靜荷載,分析瀝青混凝土的溫度、半剛性材料回彈模量、復(fù)合地基材料參數(shù)和厚度對(duì)路表的最大彎沉、殘余變形、基層和底基層層底的徑向應(yīng)力的影響。
