Snake movement experiment table for railway vehicle bogie

Abstract

The invention discloses a snake movement experiment table for a railway vehicle bogie which can be used for carrying out in-depth teaching and research of the snake movement of the railway vehicle bogie. Therefore, the snake movement experiment table for the railway vehicle bogie comprises a rail and a bogie which is mounted on the rail and capable of moving along the rail. The bogie comprises a front wheel pair, a rear wheel pair and a framework connecting the front wheel pair and the rear wheel pair. The rail is provided with a testing section capable of simulating practical rail lines, and a first sensor module and / or a second sensor module and / or a third sensor module are arranged on the experiment table, wherein the first sensor module is used for acquiring the motion parameters of the framework, the second sensor module is used for acquiring the motion parameters of the front wheel pair and the third sensor module is used for acquiring the motion parameters of the rear wheel pair when the bogie runs on the testing section. The first sensor module and / or the second sensor module and / or the third sensor module are in signal connection with a data processing system for calculating and outputting related data of sway and head shaking of the framework and / or the front wheel pair and / or the rear wheel pair.

Description

technical field [0001] The invention relates to a railway vehicle bogie snaking motion experiment platform which can be used for teaching and scientific research. Background technique [0002] The snaking motion characteristic of a railway vehicle is an important index in its dynamic performance, which directly affects the design of the vehicle and the improvement of its running speed. For railway-related colleges and universities and other teaching institutions, it is very important to provide students with a real demonstration of vehicle snaking motion, and to truly understand snaking motion through experimental data measurement and processing. For railway-related research units, through bogie snaking experiments and numerical simulations, theory and practice can be combined to study the influencing factors of bogie snaking motion, explore new theories and calculation methods, and further promote railway vehicle snaking motion The research can provide a certain reference ...

AI Technical Summary

Problems solved by technology

At present, the main equipment that can be used for railway vehicle snaking motion experiments is the locomotive vehicle rolling vibration test bench, the EMU bogie rolling vibration test bench, and the bogie critical speed test bench. These experimental equipment cannot collect data that reflect the bogie motion process. It is difficult to carry out in-depth research on the stability of bogie snaking motion due to data related to snaking motion

Given the lack of intuitiveness and operability of these experiments, it is difficult to use them for teaching

At present, the teaching of snaking movement is mostly limited to classroom explanations, and there is a lack of experimental links, so the learning effect of students is not good
