At Irkutsk State Transport University (IrGUPS), a digital twin for train braking systems has been developed. The innovation makes it possible to model and predict brake performance in real time, significantly improving the safety and efficiency of trips on Yermak-series electric locomotives on the East Siberian Railway.
Head of the Technology Transfer Center Pavel Ivanov said that the system includes three main modules. The first of them — "Digital Twin of the Braking System" — is specialized software installed on the locomotive's onboard computer. Virtual sensors transmit important data to the digital model.
The second module — "Driver's Assistant" — analyzes trip scenarios, creating a mathematical model that helps predict possible situations and braking events based on the parameters set by the driver.
A diagnostics module is also provided, which uses virtual sensors to transmit data and helps promptly identify faults related to leaks, spontaneous brake activation, and loss of efficiency.
Modeling processes in braking systems requires 100 times more time than the actual operation of rolling stock. The digital twin makes it possible to significantly speed up this process, preventing errors and accidents.
