由于在微纳操作、能量捕获、先进传感等系统中的成功应用,空间平动柔性并联机构的市场需求与日俱增,促使对空间平动柔性并联机构设计方法的研究炙手可热。提出了一个基于位置空间概念的空间平动柔性并联机构的系统设计方法(简称为PSBD方法)。PSBD方法主要用于系统设计3腿(即无冗余柔性腿)空间平动柔性并联机构。首先介绍了空间平动柔性并联机构及其基本的设计要求,然后提出了PSBD方法并阐述了其基本原理和实现步骤,继而通过实例的方式详细解释了PSBD方法所涉及的关键技术问题。利用所提出的PSBD方法,即使是初级设计师也能够设计出具有结构多样,运动解耦,驱动独立和伴生运动小等特性的空间平动柔性机构。

It has been experiencing a rapid increase in the research on the design of spatial translational compliant parallel mechanisms, due to their various applications such as micro/nano-manipulation, energy harvesting and advanced sensors. A position-space-based design (PSBD) approach to the design of spatial translational compliant parallel mechanisms is proposed paper. The PSBD approach is mainly employed to systematically design basic, i.e., three-legged without redundant legs, spatial translational compliant parallel mechanisms. Spatial translational compliant parallel mechanisms and their general design requirements are described, and then the PSBD approach is proposed. In order to show the relevant techniques of the PSBD approach, a spatial translational compliant parallel mechanism is designed using the PSBD approach, as a design example. It can be seen that not only experts but also beginners can design a great number of decoupled spatial translational compliant parallel mechanisms with actuation isolation and small parasitic motion.
