Workspace Analysis for Parameter Optimization of a Cable-driven Boat Motion Simulator

The cable-driven Boat Motion Simulator is a mechanical system designed to replicate the intricate 6 degrees of freedom motions experienced by a boat. This simulator consists of 8 cables and a moving platform. The platform is connected to the cables, and its position is controlled by actuating motors that adjust the cable lengths accordingly. To accurately replicate the desired boat motions, optimizing the design parameters that offer sufficient workspace for the simulator is crucial. This paper focuses on analyzing the workspace using three design parameters: height, width, and cable attachment points. Examining the workspace under various parameter configurations aims to optimize the design and ensure that the simulator provides a sufficient range of motion to replicate complex boat motions accurately. To assess the workspace, we developed a simulation model and an algorithm incorporating three methods: static equilibrium analysis, cable-to-cable interactions, and cable-to-platform interference detection algorithm. This research provides insights into achieving an optimized design for the Cable-driven Boat Motion Simulator, enabling realistic boat motion replication.
