Coconut Creek (Florida), ISSN 0749-0208.In this paper, the evacuation process of the vertical slide Marine emergency evacuation system and the force under different states of the system are analyzed and explored. The overall scheme of Marine emergency evacuation system with vertical slide is established. The movement of escaping personnel falling in the chute system is deeply analyzed. The slide system is divided into a network-man model and a load-bearing steel cable model. On this basis, the steel-flexible body contact model (that is, the “ball-net” collision model) and the single-side fixed series multi-degree-of-freedom vibration model are established. And the mathematical exploration and simulation analysis. In the process of analysis, the falling speed, falling angle and boundary conditions of simulation analysis were determined one by one, and the analysis result was the load output of the top of the load-bearing steel cable. The simulation results are in line with the expected estimation. After optimizing the results of the slide dynamic analysis, the dynamic response of the space steel frame is analyzed as the input condition of the dynamic analysis of the space steel frame, and the results meet the expected requirements.
