Abstract: Abstract It is important for designers of mechanical systems to visualize as many kinematic structures of mechanisms as possible. In this paper, a systematic methodology is proposed to generate all solutions of planar 8-bar kinematic…

Abstract: Abstract This paper proposes a new-kind three-translational and two-rotational (3T2R) motion with one fixed and one variable rotation directions. The serial kinematic chains (SKCs) that generate the proposed motions are synthesized. They are quite different…

Abstract: Abstract For mechanism design, the isomorphic kinematic chains (KCs) should be deleted to improve design efficiency. At present, most methods of isomorphism detection involve complex concepts and comparison of intermediate parameters. Moreover, when the number…

Abstract: Narrow passages in free space pose great challenges to many sampling-based motion planners. In problems with high-dimensional configuration spaces (C-spaces), narrow passages in free space (C-free) can be hard to find and navigate and, sometimes,…

Abstract: An important step in the structural synthesis of kinematic chains (KCs) or mechanisms is the detection of isomorphic structures. Although many detection methods have been proposed, most of them require complex computations and have poor…

Abstract: This paper introduces the concepts of influence matrix and influence map for actuated kinematic chains. The influence matrix and influence map are defined to provide the designer with methods to identify and map actuators dependency.…

DOI: 10.15632/jtam-pl/116580
Abstract: This paper presents a new method for calculating maximal collision forces in kinematic chains based on their impulses. Its main advantage is its simplicity as it is based on algebraic equations. Collisions between the feed,…
