چکیده

This paper presents the Eclipse-11, a new six degree-offreedom parallel mechanism, which can be used as a basis for general motion simulators. The Eclipse-I1 is capable of x, y and z-axis translations and a, b and c-axis rotations. In particular, it has the advantage of enabling continuous 360-degree spinning of the platform. The computational procedures for forward and inverse kinematics of the Eclipse-I1 are described. Next, the complete singularity analysis is presented for the two cases of end-effector singularity and actuator singularity. Two additional actuators are added to the original mechanism to eliminate both types of singularity within the workspace.

A New Fighter Simulator Based on a Full Spinning Six Degrees-of-freedom Parallel Mechanism Platform

This paper presents an innovative motion base for flight simulator, which is based on the new six degrees-offreedom parallel mechanism, called ‘Eclipse-II’. Most conventional simulators adopt the Stewart platform as its motion base. The Stewart platform is a six degree-of-freedom parallel mechanism that enables both translational and rotational motions. However, the motions such as continuous 3...

Design of a Parallel Mechanism Platform for Simulating Six Degrees-of- freedom General Motion Including Continuous 360-degree Spin

This paper presents a new six degree-of-freedom parallel mechanism platform, which can be used as a basis for general motion simulators. The unique feature of the platform is that it enables unlimited continuous 360-degree spin in any rotational axes plus finite X, Y, and Z-axis translation motion. The first part of the paper deals with the kinematic design issue of the platform including singu...

Kinematic and Dynamic Analysis of Tripteron, an Over-constrained 3-DOF Translational Parallel Manipulator, Through Newton-Euler Approach

In this research, as the main contribution, a comprehensive study is carried out on the mathematical modeling and analysis of the inverse kinematics and dynamics of an over-constraint three translational degree-of-freedom parallel manipulator. Due to the inconsistency between the number of equations and unknowns, the problem of obtaining the constraint forces and torques of an over-constraint m...

The 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...
