Test device for simulating contact collision during floating butt joint of offshore electrical platform

The invention provides a test device for simulating contact collision during floating butt joint of an offshore electrical platform, which comprises a vibration table, a constraint frame and an upper block test model, and is provided with a data acquisition module for processing multidirectional data in a response process; an object placing table is arranged at the top of the excitation device in the vibration table, a reserved base is arranged on the object placing table, and meanwhile a spacer region is arranged between the constraint frame and the object placing table; the restraining frame comprises a longitudinal supporting frame and a transverse supporting frame which are arranged above the storage table and connected with each other. By simulating the most unfavorable butt joint collision working condition in the floating support installation process of the large offshore electrical platform, the butt joint collision load mechanism and the structure-equipment coupling vibration response are disclosed,
