The invention discloses a wing flutter model frame segment structure, and belongs to the technical field of flutter test device design. The wing flutter model frame segment structure comprises a metalbeam, a leading edge, a trailing edge, a skin cover plate, common ribs, a reinforcing rib, a self-locking device, a self-locking push rod and clamping pins, wherein the leading edge, the trailing edge and the common ribs at the left and right sides are mutually connected to form a main frame, and the reinforcing rib is arranged in the main frame and used for connecting the leading edge and the trailing edge; the metal beam passes through the common ribs and the reinforcing rib and is connected with the reinforcing rib so as to install the whole main frame on the metal beam; the skin cover plate is provided with skin ribs with the clamping pins and limited on the common ribs at two sides through the clamping pins; one end of the reinforcing rib is provided with the self-locking device, andthe skin cover plate is provided with the self-locking push rod; and the skin cover plate is detachably installed on the main frame through the cooperation of the self-locking push rod and the self-locking device. In the test process, the wing flutter model frame segment structure can effectively save the test time and reduce the test cost, ensures the smooth and neat appearance of the frame segment and improves the accuracy of the test result.
