摘要：
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. © 2020 Journal of Mechanical Engineering.
