Abstract

The invention discloses an anti-crash design method for a helicopter fuel system. The anti-crash design method for the helicopter fuel system comprises the following steps of 1, building a fuel systemsimulation model, wherein the fuel system comprises a fuel tank cabin, a soft fuel tank, fuel or water, easily broken connecting pieces, an accessory plate and protective foam; 2, setting parametersof unit materials according to actual parameters of the materials; 3, performing boundary and contact definition; and 4, through comparison of a calculation result and a test result, correcting basicparameters of an anti-crash simulation analysis finite element model of the fuel system. According to the anti-crash design method for the helicopter fuel system, the workload of anti-crash testing ofthe helicopter fuel system can be greatly reduced; the design cycle is shortened; and huge economic benefits are generated.

Description

technical field [0001] The invention relates to the technical field of anti-crash design and analysis of a helicopter fuel system, in particular to a method for anti-crash design of a helicopter fuel system. Background technique [0002] In helicopter crashes, nearly all fires are caused by fuel leaks from the crash. In most survivable accidents, an anti-crash fuel system prevents a crash fire or delays it long enough to allow occupants to escape. Simulation analysis is very important in the anti-crash design of helicopter fuel system. [0003] The research on anti-crash of the helicopter fuel system in the prior art is mainly based on the test, and the drop test method is mainly used, which has the disadvantages of long design period, high test cost, and complicated design changes. [0004] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. Contents of the invention ...
