Once the structures step into inelastic work state , the earthquake input energy is dissipated by the damp and inelastic distortion 结构一旦进入非线性阶段,其地震总输入能主要由结构的非弹性变形和阻尼来耗散。
Therefore , it is safer to take elastic deformation of floors into account in the practical spatial analysis and design 因此,对于空间结构的分析与设计,在实际中应考虑楼板的弹性变形,这样更接近其实际状态,使设计更安全、更可靠。
Abstract : algebraic methods and rapid deforming techniques are used togenerate three - dimensional boundary - fitted dynamic grids for assemblies 文摘:采用代数方法、局部变形技术及快速动态弹性变形技术生成三维翼/体组合的贴体动态网格。
The elastic deformation of the transmission shaft and the bearing , the drive of the mesh toughness , error and mesh impact were considered in the model 模型中考虑了传动轴和轴承的弹性变形以及齿轮的啮合刚度激励、误差激励和啮合冲击激励。
Based on the creep experimental data of shale , the relationship between stress level , time and visco - elastic deformation disciplines of rock is analyzed 本文在页岩蠕变试验数据的基础上,分析了岩石粘弹性变形随应力水平不同和时间发展的变化规律。
Valve gear is regarded as stiffness in the traditional design and its elastic deformation in motion is neglected . this method is called static design 配气凸轮传统的设计方法是把配气机构看成绝对刚体,不考虑它在运动时的弹性变形,这种设计也称为静态设计。
Compliant mechanisms ( cm ) can be defined as mechanisms that gain some or all of their motion due to the relative flexibility of their members 柔性机械是利用构成机械的零部件的弹性变形来实现设计功能的一类机械。其特点是在柔性机械中存在较少的或者不存在刚性副和刚体。
The other is more accurate for the case where the elastic deformation of the ring is relatively large compared to the initial clearance 其一适合用于当圆环弹性变形相对小于转子和外壳的起始间隙时,另一法用于当圆环弹性变形相对大于转子和外壳的起始间隙时可得较精确的结果。
But that of supper quiet fixed structure can not be computed only with quiet equilibrium condition , it must be considered the flexible deformed coordinative condition of structure in same time 超静定结构的支座反力和各截面的内力不能完全出静力平衡条件叩。地确定,必须考虑结构的弹性变形协调条件确定之。
However , in fact , cam has elastic deformation and all parts from follower to cam also have deformation . so elastic deformation of valve gear must be considered in design 然而事实上凸轮本身是有弹性变形的,从气门到凸轮轮廓的中间环节也都是可变形的,所以在设计中必须考虑到配气机构的弹性变形,这种设计称为动态设计。
