Model of Electric Train Pneumatic System

Print

The studies have shown that existing diagnostic techniques for the pneumatic system within an electric train have low reliability, completeness and diagnostic depth.

To identify the diagnostic features that characterize different types of faults and the degree of their development, a large number of test data for each type of fault needs to be collected. In practice to do this work within a reasonable period of time is not possible. This raises the problem of modeling dynamic processes in the pneumatic system of the electric multiple unit with different types of faults.

As follows from the analysis of possible methods it was decided to model gas-dynamic processes in the pneumatic system of the electric multiple units using the combined method, i.e. some parts of the pneumatic system would be described analytically, the other parts – algorithmically. Modeling the system as a whole will be done by numerical method of finite differences.

The resulting model accurately describes the gas-dynamic processes in the pneumatic system of the electric multiple unit. After being improved with regard to pipelines it can be applied for modeling various types of faults in the pneumatic system.
