Abstract

The invention relates to an all-parameter customized type dropper three-dimensional pre-configuration method and system. The method comprises the steps: adding an all-line three-dimensional world coordinate system for modeling in a dropper pre-configuration process; adding weight reduction models of all types of additional loads; defining the position of each dropper, the position and tension of an elastic sling and the position and weight of an additional load; adding a midspan dropper point height correction algorithm, adopting a finite element calculation method, calculating three-dimensional coordinates of a full-line contact network to calculate an accurate solution of the dropper length is solved. A full-line and full-parameter customization mode is adopted, the problems that an existing method cannot be applied to differential design and existing railway transformation customization calculation are solved, a three-dimensional space modeling mode is adopted, and the calculation precision is improved compared with the existing method. According to the method, a good engineering application effect is obtained, and through inspection, on the premise that all links are accurate,dropper calculation under all working conditions can be achieved, and the dropper can be installed in place at a time.

Description

technical field [0001] The invention relates to the field of catenary hanging string preconfiguration, in particular to a catenary hanging string preconfiguration method and system with full parameter customization. Background technique [0002] Pre-configuration of suspension strings of railway catenary is an important part of railway catenary construction. The results of pre-configuration of suspension strings directly affect the safety of trains, the quality of train intake, and the life of pantograph slides and catenary wires. [0003] With the development of high-speed railways, the speed of trains continues to increase, the smoothness of the contact line becomes more and more important, and the precision requirements for suspension strings are getting higher and higher. The three-dimensional space calculation method is used to replace the existing simplified plane calculation method. Calculation accuracy can be improved. [0004] As China's railway catenary gradually ...
