Embodiment Construction
[0022] The present invention is described in further detail now in conjunction with accompanying drawing.
[0023] figure 1 It shows the precise layout and positioning process of the space position of the track plate involved in the present invention.
[0024] As shown in the figure, the precise layout and positioning process of the spatial position of the track slab includes the following steps:
[0025] 1. Create a three-dimensional space curve model of the left and right lines of the line
[0026] First, create a plane model of the left line of the line, input line plane data and broken link data into the computer, create plane curve set units (including transitional curves, circular curves, and transitional curves), create curve clip line units, add curve superelevation data, and form flat model. There are two ways to input line plane data: ① Input the plane coordinates of the intersection points and the curve radius at each intersection point, the length of the transit...

The invention discloses a method for accurately arranging and positioning the spatial position of a track slab for three-dimensional continuous track systems, and the method comprises the following steps: determining the arrangement range of the track slab for the three-dimensional continuous track systems through creating a three-dimensional spatial curve model for left-right lines of a route, thereby determining the longitudinal position of the track slab along the left-right lines of the route; accurately determining the horizontal position of the track slab relative to the left-right lines by using the position relationship between a control point and the left-right lines; and finally, outputting the arrangement result of the track slab. The method disclosed by the invention is applicable to any three-dimensional continuous track systems, has the characteristics of good universality, high degree of automation, high precision of acquired data, high efficiency, and the like, and has an obvious application effect.
Description
technical field [0001] The invention relates to a method for arranging and locating the space position of a track slab, in particular to a method for precisely arranging and locating the space position of a track slab in a three-dimensional space continuous track system. Background technique [0002] China's railway construction is in a period of development and speed-up. High-speed railways have the characteristics of high operating speed, high requirements for smoothness, and high requirements for laying accuracy. Traditional track structures can no longer meet the operational requirements of high-speed railways, and many new track structures have emerged in large numbers. For the new three-dimensional space continuous track system, only by accurately arranging and positioning the space position of the track slab, can it meet the requirements of high precision, high ride comfort, and high comfort for its laying and operation. [0003] Because the traditional track structu...
