...-structures, namely, the carriage and the parallel manipulator. The welding process is carried out continuously along the track rail mounted on the inner surface of the VV sector to ensure continuous weld joint. The machining process is carried out in cycles and the robot can provide high stiffness and high...

...Shiqi Li; Dong Chen; Junfeng Wang Purpose This paper aims to present a method of optimal singularity-free motion planning under multiple objectives and multiple constrains for the 6-DOF parallel manipulator, which is used as an execution mechanism for the automated docking of components. Design...

...Dianjin Zhang; Guangyu Zhang; Longqiu Li Purpose This paper aims to provide a simple and flexible calibration method of parallel manipulators for improving the position accuracy only using partial pose information. Design/methodology/approach The overall idea of this method is to use BP neural...

... on the motion precision of parallel manipulators. Design/methodology/approach The flexible dynamics model of the links is first established by applying the Euler–Bernoulli beam theory and the assumed modal method. The rigid-flexible coupling equations of the parallel mechanism are further derived by using...

...Yanbing Ni; Biao Zhang; Wenxia Guo; Cuiyan Shao Purpose The purpose of this paper is to develop a means of the kinematic calibration of a parallel manipulator with full-circle rotation. Design/methodology/approach An error-mapping model based on the space vector chain is formulated...

...Jianjun Yao; Le Zhang; Shuo Chen; Zhenshuai Wan; Tao Wang; Qingtao Niu Purpose – The paper aims to achieve translational shaking tests on a 6-DOF hydraulic parallel manipulator. Shaking tests are commonly performed on shaking tables, which are generally used for small motion ranges...
