Abstract: A swing simulation platform with multiple degrees of freedom is a common high-precision simulation device used to reproduce motion attitudes, and it is widely applied in the shipbuilding, aviation, automotive, and amusement industries. Based on an actual swing platform development project and specific performance requirements, this paper designs the hydraulic system of the swing simulation platform, including verification of the motion laws of the hydraulic cylinders and determination of key parameters, main components, the control system, and control strategies. The theoretical methods presented have been applied to a large amusement facility for simulating swing motions, providing a feasible reference for the design of similar systems and serving as a theoretical basis for validating simulation analysis results.
