BBO Algorithm-based Structural Optimization of Transmission Line Crossing Frame
Crossing construction of high-voltage transmission lines is a high-risk special construction project.During the construction process,the stress on the main support rope and the stability of the crossing frame are two core parameters that affect the success or failure of entire crossing work and the safety of construction personnel.In order to deeply analyze the stress situation of steel pipe crossing frame and main support rope during crossing work,and to accurately monitor de-tailed situation of the highest risk point in crossing work,this paper applies biogeographical algorithm (BBO)to the struc-tural optimization of the crossing frame.Through ANSYS finite element simulation analysis,it performs a detailed discus-sion on the stress situation of main support rope,stay wire,and steel pipes and other structures,which has strong guiding significance for crossing construction.
