Modeling of a rigid-flexible coupled dynamic system.we derivedthe equations of a rigid-flexible coupled dynamical system by usingLagrange Method,including the rigid's space three-dimensionmotion,the beam's vibration and the non-linear joint.

针对某一刚柔耦合多体系统，应用拉格朗日方程建立了含有刚体空间三维运动、柔性体弹性振动及非线性弹性铰的较为完善的动力学方程，由此可以根据不同的实际情况进行简化而得到相应的方程，免去了重新进行烦琐推导的过程。2。

Construction methods of large-span reticulated cylindrical shell are studied in this paper, based on variety of existing spacial structure construction methods. A new type of construction method that the structure is formed integrally by sliding support is bring forward in literature [1]. Construction process run-after computation is conducted by Ansys program, and a new type of hinged joint is obtained.

本文在概括总结了现有的各种空间结构施工方法的基础上，着重研究了大跨度柱面网壳结构的施工技术，对文献[1]提出的新施工方法——柱面网壳支座水平滑移结构整体成形施工法进行了施工全过程的跟踪模拟和结构内力分析，给出了具体施工实施方法，并提出了一种可单自由度转动的新型铰接节点。

Healy's two decade long collecting passion is evident in his choice of each consummately executed piece-thirty-one objects in all-from the richly articulated textures and patterns of Yuan dynasty black lacquer boxes inlaid with mother-of-pearl, to the swirling formal tixi scrollwork, floral patterns and sophisticated narrative scenes of Ming dynasty carved lacquer.

的两个十年的长期搜集的激情，是明显的表现在他的选择，每个consummately处决件31物体都来自丰富的铰接式纹理和规律，元朝黑漆盒镶嵌珍珠母，以翻滚正式蒂克西scrollwork ，插花模式和先进的叙事场面明代刻漆。

The experiments of light-weight steel frames with four types of different semirigid joints were carried out.

在钢框架分析和设计中，一般都假定梁柱之间没有相对转动，梁柱之间夹角不变的完全刚接或者梁柱之间不能传递弯矩，只能独立发生转动的理想铰接。

A topology optimization model for the control arm of a vehicle suspension including ball joints and bushings is set up, and a topology optimization for CA is carried out.

建立了含有球铰和衬套的汽车悬架控制臂优化设计模型，利用拓扑优化技术对悬架控制臂进行了优化设计。

We wanted to create a light that was both visibly rich and articulated, starting from a very simple module.

This paper presents analytical solutions of internal forces of a solid three hinged arch subjected to complex loadings by a singular function method.

用奇异函数法导出了实体三铰拱在复杂载荷作用下内力的解析解，与传统的数解法相比，由于用统一的解析式表达内力，便于编程计算，也便于根据已知外载情况合理地设计拱轴

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
