Speech Title: Machine learning and deep reinforcement learning applied in different fields

Abstract: Machine learning (ML) and deep reinforcement learning (DRL) have the potential to bring about significant impacts in automation across various industries and domains. The talk will explain how ML and DRL techniques can be applied in different automation fields: automotive, traffic management and structural health monitoring. Moreover, in each application the role of the simulation is of basic importance for training the agents. Some case studies will be presented in different application areas.Autonomous braking systems based on an intelligent agent trained with DRL can interact with the environment, collect data and react by controlling the vehicle speed when uncontrolled events require an action. DRL approaches are used for efficiently handling by intelligent traffic lights road traffic in road intersections where priority issues are important and autonomous vehicles are involved. Innovative methods based on ML tools are used for detecting damages in steel truss railway bridges to classify raw strain multivariate time series data.

Speech Title: Locomotive Drive and Transmission System Dynamics

Abstract: Large axle loads, extended train sets, high-speed operations, and dense traffic have emerged as pivotal trends in railway transportation. However, the engineering advancements in this field have already transcended the boundaries of conventional science. A decade-long, in-depth study was conducted, focusing on the dynamic behaviors and evolution rules of the drive and transmission system in railway locomotives under complex line and operation conditions. A comprehensive locomotive-track coupled dynamics model was established, taking into account the drive and transmission systems along with the control system. The effect of the drive and transmission system on the dynamic characteristics of the vehicle system was thoroughly investigated. Furthermore, the electromechanical coupling mechanism of the drive and transmission system of the locomotive under complex internal and external excitation was explored. In addition, the generation mechanisms, operational mechanisms, and evolutionary laws of various typical faults in critical components were explored. The research achievements perfected the calculation method of the internal dynamic excitation in drive and transmission systems and further expanded and enriched the theoretical system of the vehicle-track coupled dynamics system. Besides, the research achievements have applied in the dynamic design of the drive units of a high-speed train, the operation and maintenance of the heavy-haul locomotive, and the optimized design of the mountain rack train. Additionally, theoretical guidance has been proposed for the optimization design, fault diagnosis, and intelligent operations of key components in traction power transmission systems for rail vehicles.

Speech Title: Evolution mechanism, control method and intelligent detection of rail corrugation in Mountain City Metro

Abstract: China's urban rail transit network has now surpassed 10,000 kilometers in total length, leading the world. After extensive construction, operating costs are increasing daily, and maintenance issues are becoming more prominent. Among these, the rail corrugation is a typical damage issue in metros. This report focuses on the rail corrugation on complex subway lines in mountainous cities, driven by the demand for safe operation and precise maintenance. The evolution mechanism, control method and intelligent detection of rail corrugation are systematically investigated. Firstly, the intrinsic relationship between the friction self-excited vibration of the wheel-rail system and the feedback vibration of track irregularity under various complicated metros are studied. Then, the phase relation between the wheel-rail friction coupling vibration and rail wear is explored, and the prediction model of rail corrugation is established. Next, the active control method of rail corrugation is proposed from the perspective of the optimization of vehicle-track structure system, and the passive control method of rail corrugation considering the influence of multiple factors is constructed based on the safety evaluation system. Finally, the qualitative identification technology of rail damage in different stages of network is proposed, and the 3D reconstruction method and evaluation technology of rail corrugation are established, which provides the optimization direction for the research direction of intelligent equipment for rail corrugation identification, prediction and evaluation.
