Modeling of 3 D-steady State of Catenary Dropper Length Based on Full Anchor Section
摘要
Abstract
In order to reduce the calculation deviation of dropper length, control the height of contact wire and improve power transmission, a 3D steady state model for the accurate calculation of the integrated dropper length is established. Based on 2D exact cable elements, 3D cable element is obtained with X-Y, X-Z coupled calculation planes. Based on finite element theory, contact network structure is discrete by using 3D cable element. The stiffness matrix is assembled according to the topological structure of the contact network and the boundary conditions are established based on the geographic information, measurement information and design parameters. The iterative method is employed to solve nonlinear equilibrium equations. 3D graphics and output of the integrated dropper length are fulfilled according to the results of the equations. The comparison of the calculated dropper lengths with site measurements show that the calculation errors of the single suspension masts are less than 2. 0译 and those of the transition masts are less than 3. 5‰. The results verify the validity of the 3 D model and the construction method.关键词
