Embodiment Construction

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0066] Nowadays, the development of my country's high-speed railway is advancing by leaps and bounds, and the operating mileage is also increasing. For the high-speed railway bridges in the mountainous areas of western my country, where the geographical environment is relatively complex, special geological conditions, and seismically active zones are more prominent, additional deformation will e...

Abstract

The invention provides a method and device for establishing a rail surface mapping model, and relates to the technical field of high-speed railway bridge engineering. The method includes: obtaining the structural diagram of the bridge to be built and the failure parameters of interlayer connections, establishing an overall Cartesian coordinate system of simply supported beams and upper track structures based on the structural diagram; and establishing an absolute displacement matrix of the bridge to be tested based on the overall Cartesian coordinate system; According to the interstory connection failure parameters, the interstory force matrix of the bridge to be built is established; the rail surface mapping model is generated by combining the pre-acquired simply supported beam absolute displacement matrix, absolute displacement matrix and interstory force matrix. The method and device for establishing the rail surface mapping model of the present invention can quickly and accurately determine the geometry of the rail surface after additional deformation of the bridge, and use it as an evaluation index for train operation safety, which is of great significance to the operation of high-speed railways.

Description

technical field [0001] The invention relates to the field of high-speed railway bridge engineering, in particular to a method and device for establishing a rail surface mapping model. Background technique [0002] Nowadays, the measurement of the rail surface geometry of high-speed railway tracks is mainly determined by the rail inspection vehicle detection system. Seriously affect the efficient operation of high-speed railway. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method and device for establishing a rail surface mapping model, so as to improve the technical problem that it is difficult to quickly determine the rail surface geometry of a track. [0004] In a first aspect, an embodiment of the present invention provides a method for establishing a rail surface mapping model, the method comprising: [0005] Obtain the structural diagram of the bridge to be built and the failure parameters of the interlayer ...
