In order to make passengers safe and cozy and manage the airfield better ,the advent and application of boarding bridge solves this problem successfuly. The boarding bridge is an auxiliary equipment widely used in airfield, and it connects the hall for passengers and the body of the plane. The passengers go on or off the plane through the boarding bridge, and they will feel safe and comfortable. Moreover, the faster the society develops, the more boarding bridges are needed. In the design process , how to design a boarding bridge according to the concrete situations ? On the one hand , we should reduce the cost for the maker, On the other hand, we should safeguard the passengers.So I decide to carry out the discrete optimum of the boarding bridge structures. Firstly, the thesis establishs the finite element method based on ansys. Secondly, the thesis includes most kinds of working conditions of the construction and makes a concrete analysis of concrete conditions. Finally, relations between some important parameters of boarding bridge structures and the maximum stress of it Keywords: boarding bridge structures model finite elemen
