The invention discloses a cabin structure compression-shear coupling load test device which is characterized in that the cabin structure compression-shear coupling load test device comprises a dowel bar 1, a single lug 7, a pull plate 8 and a flange plate 6, one end of the dowel bar 1 is connected with the flange plate 6 through a pin, and the flange plate 6 is used for being connected with an internal force bearing frame of a cabin test piece; the other end of the dowel bar 1 is connected with a pull plate 8, and the pull plate 8 is used for bearing shearing force; the single lug 7 is installed in the middle of the dowel bar 1, the dowel bar 1 can rotate around the single lug 7 within an angle range, and the single lug 7 is equivalent to a fulcrum of the dowel bar 1; the bottom of the dowel bar 1 bears pressure in the z-axis direction. According to the test design method provided by the invention, the problem of applying a large amount of compression-shear coupling loads is solved, and meanwhile, the size of
