Problems solved by technology
[0002] The number and variety of railway locomotive brakes are various. The existing train brake test system is difficult to adapt to different types of brake tests. High, it is necessary to strengthen the performance test and evaluation of the braking system; there are more and more types of brakes equipped with new freight trains at home and abroad, and it is necessary to continuously transform and build new test equipment
The prominent features of the train braking test are the large number of brake machines, the large number of test points and data, the long time period and huge investment for the transformation of existing test equipment and the construction of new equipment, and it is difficult to meet the requirements of train braking performance testing and safety and reliability evaluation.
