以螺旋理论为基础,提出并联机构移动自由度的实现条件,阐述了分支输入副的选择准则,确立了分支运动副的配置原则,进而形成了较为完整的移动解耦并联机构构型综合理论。根据所得综合理论,以工程实际任务要求为例,综合出三移动解耦并联机构的各分支,并选取其中三个分支组合得到一种具有全局各向同性的新移动解耦机型。针对新机构的自由度及位置正反解进行分析,以雅可比矩阵的条件数为目标进行了位形优化,并据此参数开展了样机研制。
以螺鏇理論為基礎,提齣併聯機構移動自由度的實現條件,闡述瞭分支輸入副的選擇準則,確立瞭分支運動副的配置原則,進而形成瞭較為完整的移動解耦併聯機構構型綜閤理論。根據所得綜閤理論,以工程實際任務要求為例,綜閤齣三移動解耦併聯機構的各分支,併選取其中三箇分支組閤得到一種具有全跼各嚮同性的新移動解耦機型。針對新機構的自由度及位置正反解進行分析,以雅可比矩陣的條件數為目標進行瞭位形優化,併據此參數開展瞭樣機研製。

Based on the screw theory ,the realization conditions of the translational degree of free-dom(DOF) for the parallel mechanism were proposed ,while the selective guideline of the input pair was elaborated and the configurations principles of the kinematic pair were established .All of these were to form the relatively complete type synthesis theory of the translational decoupled parallel mechanism(TDPM) .According to the obtained theory ,taking a practical engineering task as an exam-ple ,a full isotropic TDPM which was composed of three branches was achieved after synthesizing all branches of the 3-TDPM .Then the DOF and the forward and inverse solution of the new mechanism were analyzed .Finally ,the prototype was manufactured in accordance with the configuration parame-ters which were obtained on the basis of the condition numbers of Jacobian matrix .
