The invention belongs to the technical field of helicopter structure static strength design, and particularly relates to a helicopter fuel tank compartment static strength rapid calculation method. The method comprises the following steps: S1, establishing an oil tank cabin finite element simulation model, and applying constraints according to actual conditions; S2, determining the working condition of the oil tank cabin, and screening out the severe working condition of the oil tank cabin; S3, simulating inertial load distribution of the oil tank cabin body; S4, simulating the loading of thefuel oil; S5, creating a working condition that the overload is 1g in the front-back direction, the left-right direction and the up-down direction of the oil tank cabin, and submitting a software calculation static strength result; and S6, calculating the static strength of the oil tank cabin under each actual overload in a combined manner. According to the method, the static strength of the helicopter fuel tank compartment under each helicopter mission profile is comprehensively analyzed, and the time is saved; modeling key points and an analysis method are provided for finite element simulation of the oil tank compartment; and meanwhile, the method is suitable for analyzing oil tank cabins of various shapes.
