Dynamic Analysis of a 6-DOF Inverted Stewart Platform

This paper concerns the design and analysis of a 6-DOF inverted Stewart platform of an amusement park. In consideration of both the thrill-seeking and the safety of tourists, the platform must have 3 proper translational axial accelerations and 3 proper rotary angular accelerations within one motion cycle, and the impact of seismic force shall be taken into account in order to retain the adaptability to change of the system in case of emergent situations. Besides, the safety factors of various parts and components of the system shall be higher than six. In this paper, a 3D model is developed for the platform by means of Solidwork, and kinematics simulation is carried out by means of Cosmos/Motion software to generate 3D geometrical diagrams which are to be transferred into ANSYS Workbench software, and at last, the optimized design of geometry of each part/component of the system and the evaluation of overall safety of the system are conducted in Workbench software based on foresaid 3D geometrical diagrams.
