The invention discloses a loading device and method for simulating an aerodynamic load of a special-shaped cabin section. The loading device comprises a bearing base, a workpiece clamping structure and a simulated aerodynamic load loading mechanism, wherein the simulated aerodynamic load loading mechanism comprises an upper pressing plate, a pull rod and a connecting rod transmission mechanism; the connecting rod transmission mechanism comprises a pneumatic load simulation pressing plate, a connecting rod support and a triangular connecting rod; under the action of rotation power provided by the force application part, the pull rod drives the upper pressing plate, the workpiece clamping structure, the workpiece to be tested and the connecting rod transmission mechanism to move downwards together. At the moment, under the pushing of the counter-acting force of the bearing base on the corner position C of the triangular connecting rod, the pneumatic load simulation pressing plate is driven to translate towards the to-be-tested workpiece, so that a simulated pneumatic load is applied to the surface of the to-be-tested workpiece through the pressing point. Compared with the traditional loading mode, the loading device for simulating the aerodynamic load of the special-shaped cabin section by using the distributed concentrated load has the advantages of simple structure, good equivalent effect, low cost and the like.
