Type Synthesis of Three-Degree-of-Freedom Spherical Parallel Manipulators
A spherical parallel manipulator (also called an orientational parallel manipulator or rotational parallel manipulator) refers to a threedegree-of-freedom (3-DoF) parallel manipulator in which the moving platform undergoes a 3-DoF spherical motion or rotates about a fixed point. In this paper, we propose a new method for the type synthesis of non-overconstrained (isostatic) spherical parallel m...
متن کاملA New Three-Degree-of-Freedom Parallel Manipulator
In this papel; a novel spatial three degree-offreedom, that are two degrees of translational freedom and one degree of orientational freedom, parallel manipulator is proposed. The parallel manipulator consists of a base plate, a movable platform, and three non-identical connecting legs. The kinematics problems and velocity equation of the new parallel manipulator are given. Three kincis of sing...
متن کاملOptimal Synthesis of a Planar Reactionless Three-degree-of-freedom Parallel Mechanism
A reactionless mechanism is one in which no reaction forces nor moments are transmitted to the base for any arbitrary motion. This interesting property often requires to increase the total mass and the moments of inertia, leading to reduced dynamical performances. Therefore, this paper presents an optimization approach to synthesize and improve the dynamical performance of a reactionless three-...
متن کاملKinematic Design of a Three Degree of Freedom Parallel Hand Controller Mechanism
This paper presents the kinematic design of a 10 link “inparallel” mechanism for use in a three degree of freedom forcereflecting haptic interface. The mechanism linkage couples three coplanar rotary electric motor shafts to the endpoint grasped by the human operator. The linkage permits all motor housings to be supported on a common base, thereby reducing the inertia and weight that the interf...
متن کاملThe Optimal Design of Three Degree-of-Freedom Parallel Mechanisms for Machining Applications
The subject of this paper is the optimal design of a parallel mechanism intended for three-axis machining applications. Parallel mechanisms are interesting alternative designs in this context but most of them are designed for threeor six-axis machining applications. In the last case, the position and the orientation of the tool are coupled and the shape of the workspace is complex. The aim of t...
