Problems solved by technology

[0004] The current railway vehicle limit detection on the test bench can only test the static geometric profile of the vehicle, that is, the static limit, and cannot measure the dynamic limit
This makes it impossible to conduct simulation tests on the test bench whether the state of the vehicle passing the curve satisfies the dynamic limit of the vehicle. It can only be calculated through simulation instead of the real vehicle test.

Embodiment Construction

[0034] The core of the present invention is to provide a vehicle limit detection method and system.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The invention discloses a vehicle limit detection method, see figure 1 , the embodiment includes the following steps:

[0037] S101. Simulate an actual road condition and vibrate the vehicle.

[0038] The dynamic limit of the train is the outermost points of the reference contour line based on the line, and it is considered according to the most unfavorable position of the vehicle when the wheels are running on the line. In order to detect the dynamic limit of the train, it is first necessary to simulate the actual road conditions of the train.

[0039] S102. Detect the displacement of each detection point of the vehicle ...

Abstract

The embodiment of the invention provides train gauge detection method and system. The method comprises the steps of detecting the displacement of each detection point of a train and an inclination angle of the train when the train is placed under a simulated actual road condition; calculating the coordinate value of each detecting point in the same coordinate system by treating the displacement and the inclination angle as the parameters. With the adoption of the method and system, the dynamic gauge of the train can be detected in a test line, thus the computer based simulation experiment is saved, and the obtained data are real and reliable.

Description

technical field [0001] The invention relates to the field of vehicle detection, in particular to a vehicle boundary detection method and system. Background technique [0002] In my country's vast geographical environment, railway transportation is the most important way for people to travel. When railway vehicles are in operation, the most important point is safety and reliability, so that passengers can be safely delivered to their destinations. In order to ensure the safe operation of railway vehicles, the limits of vehicles must be detected before operation or during maintenance. [0003] There must be a safe space for the operation of rolling stock. Therefore, the railway stipulates the outline size that is not allowed to exceed, that is, the limit, for rolling stock and buildings and equipment close to the line. It can be said that the boundary is a reasonable space. The rolling stock gauge is the maximum limit of the rolling stock cross section. Specifically, when ...
