Motor train traction braking experimental model device

Abstract

The invention relates to a motor train traction braking experimental model device. The device is provided with a three-phase asynchronous motor connected with a base, wherein the three-phase asynchronous motor is connected with an inertial flywheel and a magnetic powder brake respectively through shafts, and the device is further provided with a braking disc connected with the magnetic powder brake. According to the motor train traction braking experimental model device, by simplifying and simulating the structure of an actual motor train unit, students at a school can conveniently and systematically grasp the principle of motor train traction and braking equipment and learn test, analysis and fault judgment methods.

Description

technical field [0001] The invention relates to an experimental model, in particular to an experimental model device for traction braking of a motor vehicle. Background technique [0002] As a convenient, fast and efficient means of transportation in modern cities, EMUs have become an important symbol of the comprehensive strength of a country's railways. At the same time, high-speed EMUs are also key equipment for the development of China's railways. However, compared with Germany, Japan, France and other high-speed railway developed countries in the world, the research and application of my country's high-speed railway system started relatively late, and the corresponding technical specifications and training system for EMUs are still not perfect. Most of the core technologies are from Germany, The introduction of Japan, France, etc. requires a large number of professional talents to digest, absorb and apply, and the cultivation of talents who master EMU technology has beco...

Problems solved by technology

[0003] At present, there are few researches on the experimental model of EMU traction braking. Most of the learning of EMU traction braking in schools stays at the stage of theoretical study or simulation through matlab, Adams and other software, which does not allow students to fully and systematically Master the principle of motor vehicle traction braking

In terms of professional practical training, although real car training can satisfy systematic mastery of principles and testing methods, the shortcoming is that the organization of training is too cumbersome, and it is easy to interfere with normal train operation

Since it is currently difficult for school students to master professional skills from the aspect of practical operation, the establishment of an experimental model of traction braking of motor vehicles has become the best way to solve the above problems
