Design and Control of a 14-DOF Motion Simulator

Motion simulators are essential for generating the precise trajectories of aircraft, vehicles, satellites, and ships. These devices meet specific requirements and help verify actual models. This paper presents a fourteen degrees-of-freedom (DOF) parallel kinematic mechanism (PKM) designed for motion simulation in an aircraft-to-satellite signal transmission model. The analysis covers kinematics, prototyping, workspace determination, and singularity analysis. The main objective of the paper is to meet the technical specifications for generating accurate motion trajectories among two mechanisms within positioning tolerance levels up to 0.01mm. The results of the design and control of the 2-6-UCUP mechanism have surpassed the requirements of the motion simulator in which the system has a workspace of ±500mm in the Y axis, ±400mm in the Z axis and the X axis depending on the length of the track, as well as fulfilling a maximum speed of up to 1000mm/s.
