The invention discloses a dynamical coupling test method for a long and straight wing wind tunnel model with a resistance rudder, which belongs to the technical field of wing dynamical coupling wind tunnel tests. The method comprises the following steps: 1, performing test preparation: selecting a high aspect ratio wing dynamical coupling wind tunnel test model with a cracking resistance rudder; 2, performing testing: opening a wind tunnel, and giving an initial wind speed; adjusting a control surface deflection angle, observing a model vibration phenomenon, collecting and recording test data,and analyzing and judging whether to change a control surface deflection angle or increase a wind speed in the next step; and 3, performing parameter adjustment: if variable deflection angle and variable wind speed tests for a certain model state are completed, changing model parameters. The dynamic coupling phenomenon of the high aspect ratio wing with the cracking type resistance rudder is researched through a wind tunnel test method, and compared with numerical solution, the wind tunnel test method is more effective, more convenient and faster.
