Optimal Synthesis of Four‐bar Linkage Path Generation through Evolutionary Computation
2 Sustainable and Infrastructure Research and Development Center, Department of Mechanical Engineering, Faculty of Engineering, KhonKaen University, KhonKaen City, Thailand ABSTRACT: This paper presents the optimization of path generating of four-bar linkages using evolution algorithms (EAs). The design problem is assigned to minimize the error between desired and obtained coupler curves. Such ...
متن کاملDynamic Behavior Analysis of a Planar Four-bar Linkage with Multiple Clearances Joint
In practice, clearances in the joints are inevitable due to tolerances, and defects arising from design and manufacturing. In the presence of clearance at a joint, a mechanism gains some additional, uncontrollable degrees of freedom which are the source of error. Moreover, joints undergo wear and backlashes and so cannot be used in precision mechanisms. In this study, the dynamic behaviour of ...
متن کاملAn Extension of an Algorithm for Planar Four-bar Path Generation with Optimization
This work is an extension of the authors’ published work on a planar four-bar motion generation search algorithm with Grashof, transmission angle and linkage perimeter conditions [1]. This latest work considers planar four-bar path generation with a coupler point load, crank static torque, crank transverse deflection and follower buckling in a modified search algorithm. As demonstrated in the e...
متن کاملOn the Synthesis of a Reactionless 6-dof Parallel Mechanism Using Planar Four-bar Linkages
This paper addresses the synthesis of a novel reactionless spatial 6-DOF parallel mechanism using four-bar linkages without any counter-rotations. The mechanism is first described and its kinematics is discussed. A numerical example of the reactionless 6-DOF mechanism is given in this paper and, with the help of the dynamic simulation software ADAMS, it is shown that the mechanism is reactionle...
متن کاملSynthesis of Planar, Compliant Four-Bar Mechanisms for Compliant-Segment Motion Generation
Compliant four-bar mechanisms treated in previous works consisted of at least one rigid moving link, and such mechanisms synthesized for motion generation tasks have always comprised a rigid coupler link, bearing with the conventional definition of motion generation for rigid-link mechanisms. This paper introduces a new task called compliantsegment motion generation where the coupler is a flexi...
