Abstract In the aircraft structure design, we need process two kinds of data. One is the data which have been discretized by the upstream specialty and provided in grid form, such as the aerodynamic loads on the Wing and the hatch, the inertia load of structure, fuel, equipment, payload and so on. The other is the data of load which acts in form of uninform or linear distribution such as pressure of pressured cabin or fuel tank. Aircraft structure applying distributed body force and distributed surface force are mainly composed of panels, frame webs and so on. Generally, they are simplified into triangular, rectangular and quadrilateral plane stress elements. In this paper, the equivalent nodal load shift processing algorithm of three kinds of typical units is studied according to the principle of energy equivalence, and the algorithm of discrete processing of distributed load is put forward, and the rationality of the processing method of the load moment component of the discard node in practical application is explained and verified. It is proved by an example that the proposed algorithm can be popularized and applied in practical engineering.
