In order to study the modeling criterion and method of high-aspect-ratio flexible wing structure(HARFWS),accumulated linearization(AL) and equivalent rigid(ER) are utilized to explore and solve the above problem in this paper. Through numerical simulation and analysis,the proposed approach with AL and ER can not only provide the HARFWS modeling,but also give the solution that satisfied engineering accuracy requirement. Finally,seven steps are offered about the process of modeling and this can realize the modeling and solving of HARFWS.
