The method is then used to analysis the pulling stress of the film . 3 ) under the above nonlinear dynamics analysis , an optimized design has been firstly realized under virtual manufacturing environment 3 )在非線性動力分析的基礎(chǔ)上,首次在虛擬制造的條件下,實現(xiàn)了高速攝影機抓片機構(gòu)的優(yōu)化設(shè)計。
With the aid of the obtained fundamental solutions and the continuity conditions of stress and displacement on material interface , complex potentials solutions for an bi - material infinite plate with an elliptical inclusion under pulling stress are given 根據(jù)界面上應(yīng)力和位移的連續(xù)條件,得到了單向拉伸狀態(tài)下,含有橢圓夾雜的無限大雙材料組合板的復(fù)勢解。
Forces could be various and complicated , but all the complicated forces inside human body could be divided into 3 categories : pulling force , pressure and tension ; and there exists the respective stresses : pulling stress , compressive stress and tensile stress 這三個要素缺一不可,力的表現(xiàn)形式是多樣性和復(fù)雜的,但在人體內(nèi)不管多么錯綜復(fù)雜的力均可以概括為三種力的形式:即拉力、壓力和漲力,同時存在相對應(yīng)的應(yīng)力,即拉應(yīng)力,壓應(yīng)力和漲應(yīng)力。
The critical current and ac losses in hts tapes were measured under different winding radii and pulling stress . a theoretical model was proposed to describe the relationship of critical currents and ac losses with the winding or pulling stress - strain . it is shown that the calculated values were in agreement with the measured results quite well 實驗測量了高溫超導(dǎo)帶材在不同彎曲半徑及不同拉伸應(yīng)力下的臨界電流與交流損耗;建立了高溫超導(dǎo)帶材的交流損耗和臨界電流隨彎曲與拉伸應(yīng)力?應(yīng)變變化的理論模型;利用該理論公式計算的結(jié)果與測量結(jié)果符合得相當(dāng)好。
3 . base on the numeric method of finite element , the influence of interrelated shift coefficient and tooth number z to bend intensity of gear is studied . with the increase of the tooth number , tooth root maximum pull stress decrease ; with the increase of the interrelated shift coefficient , tooth root maximum pull stress increase 3 、基于有限元數(shù)值計算方法,分析了不同關(guān)聯(lián)變位系數(shù)和齒數(shù)z對齒輪彎曲強度的影響:隨著齒數(shù)的增大,齒輪最大拉應(yīng)力減??;關(guān)聯(lián)變位系數(shù)越大,齒輪最大拉應(yīng)力越大。
