In order to simulate the swing conditions of a suspended platform of a construction shaft, marine ships, cars, etc., an incompletely restrained cable-suspension swing system driven by two cables (IRCSWs2) was designed and parameter trajectories of displacements, angles and tensions were systematically investigated. Firstly, the motion mechanism of the IRCSWs2 is described and the corresponding kinematic model is established. For further evaluating the analytical expressions, the ADAMS simulation model and the physical prototype experimental model were developed. The basic consistency and slight difference among the three models are illustrated by a comparison of different parameters. The approximately linear relationship between the driving displacements of two cables and the swing angles of the platform was obtained. Finally, the effects of various parameters on displacements, angles and tensions were analysed, and the results indicate that the translation of a suspended platform is slight during its swing and that the novel IRCSWs2 can be used to drive heavy loads using a relatively small driving force, which is useful for simulating swing environmental conditions long-term, in addition to being cost-effective
