The invention provides a test device for simulating dynamic response of a marine riser wellhead coupling system under effect of uniform flow. The test device comprises a top movement module, a tensioner module, a marine riser end fixing module, a marine riser model, a conduit soil simulation module, a bottom movement module and a measurement and analysis module. The simulated marine riser model isdriven by the top movement module and the bottom movement module to move in the uniform flow; the mounting position is accurately positioned through a rail of the top movement module, and seamless connection of a vertical pipe is guaranteed; fine adjustment and accurate measurement are realized through vertical guide rails of the tensioner module and the top movement module; strain data of the vertical pipe is obtained through the measurement and analysis module; the vortex-induced vibration response characteristic of the riser under uniform flow is obtained by utilizing hydrodynamic analysissoftware for data process
