Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with accompanying drawings and embodiments, but those skilled in the art should know that the following embodiments are not the only limitation to the technical solution of the present invention, and any work done under the spirit of the technical solution of the present invention Equivalent transformation or modification shall be considered as belonging to the protection scope of the present invention.

[0037] like figure 1 and figure 2 As shown, according to the regulations of GB 1589-2016, the passability test is required to be carried out on a passage circle with a radius of 12.5m. Therefore, a vehicle passage circle track test system provided by the present invention is set around a ground circle with a radius of 12.5m. The system includes a rotatable column 1 installed at the center point of a circle with a radius of 12.5m on the ground, and an angle sensor 2, a distance measuring sensor 3, ...

Abstract

The invention discloses a vehicle turning circle track test system and method used for testing the turning circle passing of an automobile, a trailer, and an automobile train. A rotatable column is arranged, and an angle sensor, a distance measurement sensor and an image acquisition device are fixed to the column and are connected to a computer. A vehicle to be tested is provided with an image and / or distance collection mark, a distance measurement sensor mark position or an initial distance between a vehicle wheel shaft head and a wheel edge in a turning circle are recorded and are used for computer software data correction. In a test, the vehicle to be tested walks along the periphery of the turning circle, the image acquisition device acquires the mark on the vehicle in many times circularly, the angle and distance of the mark are synchronously measured in each time, then all angle and distance data are fitted, the track of the mark is formed, and the diameter of the turning circle is calculated. The system and the method have the advantages of simple operation and a small error, a track is formed in the computer, and the environment is not polluted during a collection process.

Description

technical field [0001] The invention belongs to the performance testing technology of automobiles or automobile trains, and in particular relates to a test and evaluation system and method for the passing ability of automobiles or automobile trains on circular passages. Background technique [0002] In July 2016, my country promulgated and implemented the "Outline Dimensions, Axle Load and Quality Limits of Automobiles, Trailers and Automobile Trains" (GB 1589-2016), which clarified the test standards for vehicle passability (passage circle) Define, specify the route to drive and test requirements. However, the standard only mentions test requirements and indicators, and does not provide guidance or regulations on specific test equipment and methods. [0003] The passability test method of traditional automobile or automobile train channel circle mainly comprises ground marking method (sprinkling water, spraying paint, drawing line) and GPS positioning method at present. Wi...
