After synthetically studying the effects of loading positions , rim thickness , circular pinion numbers and fillet radii of gear hob on root section stresses , a judging formula of plane stress and plane strain is proposed and verified , then 2d and 3d fem models are accurately established 系统探讨了加载位置、轮缘厚度、周向齿数的确定方法,分析了滚刀顶部圆角对齿根应力的影响,提出了两类平面问题的判据并予以验证。
In the course of stowage of heavy article , officers and engineers concertrat their attention on the calculation of vessel " s parameters and the limitation that be bringed by many factors to loading position , and don " t think much of the affection of awkward lengthy cargo " space size to loading position 在一般的重大件货物积载过程中,往往侧重于船舶的吃水、吃水差、稳性高度和倾角各参数及各因素对装货位置的限制,不太重视重大件货物的空间形状大小对装货位置的影响。
In this paper , a three dimensional finite element analysis has been used to analyse the loading stress of utw pavement . the critical loading position of utw plate and the rules of the effect of the joint spacing of plate , the thickness of overlay , ec / es and the interface conditions between concrete overlay and existing ac on the stress are provided 本文采用三维有限元法分析了utw路面荷载应力,确定了路面板的临界荷位,得出了板接缝间距、厚度、板与地基模量比( ec es )和层间接触状况对应力的影响规律。
Then , author introduces geometric nonlinear analysis theory , geometric nonlinear calculation theory during construction period , load position of live load considering geometric nonlinear and calculation theory of worst - case value , static time history theory for vehicle running , geometric nonlinear analysis theory of natural vibration and structural dynamic reaction and so on . all of these theories fit any appointed structure with corresponding programs . so a series of completed analysis approaches that cover all geometric nonlinear factors of bridge structure are formed 其次,介绍了对任意指定结构的几何非线性分析原理、施工阶段几何非线性计算原理、考虑几何非线性的活载加载位置与最不利值的计算原理、车队行驶静力时程分析原理、非线性结构的自振特性和结构动力反应分析原理等,其中包含了相应的计算程序模块的编制方法,形成了一整套考虑桥梁结构所有几第日页西南交通大学博士研究生学位论文何非线性因素的桥梁结构分析方法。
The reasons to choose aspherical grads method as the principle were presented . the two spheres which were gotten from aspherical grads method and least square method were analyzed by fem software , and the deviation with the wanted aspherical surface and the maximum stress were compared under same confined condition , same loading position and loading points . also , we proved that the sphere gotten from aspherical grads method has less surface error and stress after deformation 用有限元软件分别对非球面变化梯度法和最小二乘法所获球面进行了分析,比较两种球面在相同边界条件、相同加载位置和个数下,与所需非球面的面形误差和应力的大小,证明了用非球面变化梯度法所获得的球面在变形后,面形精度更高,应力更小。
