In this dissertation, we explore the possibilities of systematically constructing largestructural mechanisms using existing spatial overconstrained linkages with only

revolute joints as basic elements.

在这篇论文中，我们探讨利用只以旋转接头为基本元素的现存受空间限制过约束机构来系统地构建大型结构机制的可能性。

The first part of the dissertation is devoted to structural mechanisms (networks) basedon the Bennett linkage, a well-known spatial 4R linkage.

该论文的第一部分专注于以贝内特机构为基础的结构机制（网络），一个众所周知的空间4R机构。

This special linkage has been used as the basic element.这种特殊的联动一直被用来作为基本元素。

A particular layout of the structures has been identified allowing unlimited extension of the network by repeating elements.

一个特定的结构已确定通过重复元素允许的网络的无限延伸。

As a result, a family of structural mechanisms has been found which form single-layer structural mechanisms.

因此，一个形成单层结构机制的结构机制家庭，已经被建立起来。

In general, these structures deploy into profiles of cylindrical surface.一般而言，这些结构被有效利用于圆柱表面的轮廓。

Meanwhile, two special cases of the single-layer structures have been extended to form multi-layer structures.

同时，单层结构的两种特殊情况已经被扩展到形成多层结构。

In addition, according to the mathematical derivation, the problem of connecting two similar Bennett linkages into a mobile structure, which other researchers were unable to solve, has also been solved.

另外，根据数学推导，其他研究中没办法解决的将两个相似的贝内特联动机构为一个移动结构的问题解决了。

A study into the existence of alternative forms of the Bennett linkage has also beendone.

一项研究贝内特机构的替代形式的存在也被完成。

The condition for the alternative forms to achieve the compact folding and maximum expansion has been derived.

另一种形式实现紧凑的重叠和最大膨胀的情况已经出现。

This work has resulted in the creation of the

most effective deployable element based on the Bennett linkage.

这项工作已经导致了基于贝内特机构最有效的可展元素的产物。

A simple method to build the Bennett linkage in its alternative form has been introduced and verified.

一个在它的替代形式上建立贝内特机构的简单的方法已经被引进并得到了验证。The corresponding networks have been obtained following the similar layout of the original Bennett linkage.

相应的网络已经紧随着原始的贝内特机构的相似布局被建立获得。

The second effort has been made to construct large overconstrained structural mechanisms using hybrid Bricard linkages as basic elements.
