摘要: 为提高空间多臂机构折展特性和操作特性等运动性能,通过多臂机构与操作物体可组成并联机构拓扑形式的设计思想,提出了一类具有折展特性和多种操作能力的空间多臂机构。定义了用于叠放折展支链的区域及策略,提出了折展支链的延伸性判别条件。基于指定区域的尺度限制,设计了具有不同自由度且满足特定叠放要求的折展支链。其次,以拓扑形式分解的方法将操作物体的工作模式进行分解表达,给出了多臂机构的结构配置形式。结果表明,基于所提方法,空间多臂机构可通过与操作物体自主释放与组合,改变拓扑形式,实现兼具折展性能和多种操作模式的设计目标。

Abstract: To improve the folding and operation performance of multiple-arm mechanism, a class of multiple-arm mechanism with deployable characteristic and multiple-operation capability is proposed by the idea that parallel mechanism can be formed by multiple-arm mechanism and operation object. The definition of the region and strategy for storing deployable chains and the proposal of the extension criteria of deployable chains are proposed. Based on the specified scale-restricted area, deployable chains with different degrees of freedom are designed to satisfy specific storing requirements. Working modes of objects is decomposed and expressed by means of topological decomposition, and the multiple-arm structure configuration is given. The results show the multiple-arm mechanism can change the topological form by autonomous release and combination with the operation object, so that it can achieve the design purpose of deployable characteristic and multiple-operation based on the proposed method.

Key words: multiple-arm mechanism, storage area, folded-deployed property, structure configuration, concurrent operation
