The articulated bridge connecting the dynamic and static platforms exhibits multiple degrees of freedom, complex mechanical environments, and significant loading conditions, making its dynamic characteristics crucial for design considerations. In this study, virtual prototyping simulation technology was employed to establish a virtual prototype of the transshipment system comprising both the transshipment vehicle and transfer bridge model. Utilizing a rigid-flexible coupling computational approach, key load-bearing components were identified and subjected to dynamic analysis. The system was subsequently simulated under various operational conditions to investigate its dynamic responses and derive characteristic response patterns to different input parameters. This research provides valuable data references for optimizing transshipment strategies and informing the design of bridge-type transshipment models.
