刚体位移 meaning in Chinese
rigid body di lacement
rigid body displacement
Examples
- When cable interacted under the load both of gravity and inertia force , derivative equation of cable ' s defection curve in space is deduced to study cable ' s rigidity movement , and flexible deformation is also determined by finite element method
分析了悬索上各离散点的位置、速度、加速度和惯性力。推导了在重力和惯性力共同作用下悬索的空间挠曲线微分方程，并研究了悬索的刚体位移和弹性变形。 - Integrated optomechanical analysis devides rigid - body and aberration , then computes the pv and rms . it provides guidance for design , tolerances allocation and alignment of optomechanical system . finally , abberations are converted to a sort of data form that can be imported by corresponding optical design software to observe their impact upon the optomechanical system imaging performance
光机集成有限元分析方法就是通过分离三种形式的刚体位移和光学表面畸变的pv值和rms值，指导光机系统的设计、误差分配和装调，并将数据转换成光学分析软件codev可接收的数据形式，对光机系统做整体成像性能评价。 - The research result indicated : for the strip primary mirror discussed in this article , the hexagon light - weighted cell has the best structural rigidity quality , the square cell is a little worse , the triangle cell is the worst ; there is an optimum on primary mirror thickness ; on condition of 1g gravity load combining with 4 centigrade uniform temperature rising , the thinner and higher of the flexible support reed , the better of the primary mirror surface figure . the decision of the structural parameters of the flexible support reed must take static rigidity , dynamic rigidity , static strength and dynamic strength of primary mirror assembly into account
研究结果表明：对于本文的长圆形主镜，采用正六边形轻量化孔，镜体结构刚性品质最好，正方形次之，正三角形最差；主镜镜体厚度存在最佳值；主镜组件在1g重力、均匀温升4共同作用的工况下，主镜柔性支撑簧片厚度越小、高度越高，主镜综合面形误差( p - v值)越小，但同时主镜组件的刚体位移增大、固有频率下降，因此柔性支承结构参数的确定要综合考虑主镜的综合面形误差和主镜组件静态刚度、动态刚度、静态强度和动态强度等因素。 - Gram - schmidt method for zernike polynomials fit and singular value decomposition ( svd ) are concerned . the direction question for zernike polynomials fit is discussed and the surface error in the normal direction is deduced . to solve - the coupling and mixture of zernike polynomials fit method , rigid - body displacement is removed with coordinate transformation and then fitted with zernike polynomials
介绍了zernike拟合的gram - schmidt以及奇异值分解两种方法；论述了zernike拟合时的方向问题，计算了法线方向的面形误差；针对zernike拟合时的藕合与混淆，采用先用齐次坐标变换去除刚体位移，再用奇异值分解进行zernike拟合。
