在本文的第二部分中，我们演示了如何使用自由度和约束拓扑(FACT)来综合属于第一部分范围内的多自由度、并联精密柔性系统的概念，并提供了几个例子来说明第一部分中的互补拓扑和几何实体的原理如何(I)与柔性系统的特性相关，(Ii)用于可视化柔性约束的可能布局以实现期望的运动，以及(Iii)用于选择冗余约束。提出了一种综合过程，并用于可视化和构造具有必要的运动学特征和冗余约束的挠性系统概念，以提供增加的刚度、承载能力和对称性。流程的输出是一个柔性概念，然后将通过现有的建模和分析方法对其进行建模和改进。(C)2009 Elsevier Inc.保留所有权利。
In Part II of this paper we demonstrate how to use freedom and constraint topology (FACT) to synthesize concepts for the multi-degree of freedom, parallel precision flexure systems that fall within the scope of Part I. Several examples are provided to demonstrate how the Principle of Complementary Topologies and geometric entities from Part I are (i) relevant to flexure system characteristics, (ii) used to visualize the possible layout of flexure constraints to achieve a desired motion and (iii) used to select redundant constraints. A synthesis process is presented, and then used to visualize and construct a flexure system concept with the requisite kinematic characteristics and redundant constraints that provide increased stiffness, load capacity, and symmetry. The output of the process is a flexure concept that would then be modeled and refined by existing modeling and analysis methods. (C) 2009 Elsevier Inc. All rights reserved.
