Keynote #1: The Role of Dynamic Modeling of Complex Mechanical System in Sensing and Damage Detection

Dr. Jianqiao Sun, Professor, Department of Mechanical Engineering, University of California, Merced, California, USA

Abstract of the Keynote Talk:

In designing a sensor network for damage detection of complex mechanical systems, it is often difficult to have access to the signals closely correlated to the damage.  Two examples to be considered in this talk are the wheel wear of high-speed train and the bearing internal damage of steel wire drawing machines.  In both cases, it is not possible to place sensors where the wheel wear occurs or where the internal damage occurs of the bearing operating at high speed in high temperature.  We shall take high-speed train as an example and discuss an approach which relies on the dynamic model of the mechanical system and make use of large sets of accessible motion data to estimate the accumulated wear.  We leave the bearing internal damage detection as a challenge to the audience.

Keynote #2: Control and Optimisation of Vehicular Electromagnetic Suspension Systems

Dr. Haiping Du, Senior Professor, School of Electrical, Computer and Telecommunications Engineering, University of Wollongong, Australia

Abstract of the Keynote Talk:

The suspension system is a critical component of a vehicle's chassis, significantly enhancing ride quality, handling stability, and overall driving performance. However, traditional vehicle suspension systems, which typically employ hydraulic, pneumatic, and mechanical components, face challenges such as sealing issues, slower response speed, and structural complexity. In recent years, electromagnetic suspensions (EMSs) have garnered increasing attention for their ability to circumvent these challenges. EMSs offer numerous advantages, including high response speed, energy efficiency, simple structure, and enhanced controllability. This presentation will explore the latest research developments in the design of electrical networks (EN), energy efficiency optimisation, interconnection architecture, and related control technologies for EMSs. The presentation will cover the following topics: Introduction to the background, composition, and classification of EMS. Presentation of a novel mechanical-electrical analogy theory and the corresponding controllable EN. Optimisation integration design of EMSs, with an emphasis on energy-saving, energy-harvesting, and vibration control characteristics. Comprehensive overview of a novel interconnection architecture for EMS, including research motivation, decoupling structure and control algorithm, and experimental verification. Exploration of the related control technologies and strategies designed for EMS systems. This presentation aims to provide a thorough understanding of EMS advancements and their potential to revolutionise vehicle suspension systems.

Tutorial: Advances in battery health diagnostics

Dr. Akhil Garg, Associate Professor, School of Mechanical Science and Engineering, Huazhong University of Science and Technology (HUST), China

Abstract of the Tutorial:

The rapid advancement of transportation electrification in recent times has been propelled by the widespread evolution of lithium-ion battery technology as a primary energy storage solution. The crucial need of safe and efficient operation of the lithium-ion batteries has positioned the battery management system as a pivotal component in this scenario. Among its various functions, state of health (SoH) monitoring emerges as a paramount function for intelligent battery management. Achieving accurate SoH predictions not only extends the battery lifespan, but also offer significant insights for optimizing battery usage. To cater the aforementioned objectives, we aim to review the significant advancements in battery health diagnostics as well as prognostics using machine learning (ML) techniques that not only enhances the state predictions, but also simultaneously reduces the computational complexity. By delving into the current state of research in this field, this talk aims to elucidate promising future avenues for leveraging ML in the context of batteries. Furthermore, we highlight the increasing necessity for advanced remaining useful life (RUL) prediction techniques and its role in addressing the challenges associated with the surging demand on electric vehicles. This comprehensive review identifies the existing challenges and proposes a structured framework towards enhanced model training process, advanced artificial intelligence (AI) techniques, cloud-edge computing and data-distribution discrepancies. The integration of AI technologies in this endeavor is pivotal to expedite the battery performance and overcome present limitations associated with the health monitoring. In adopting a symmetrical approach, ML synchronizes with the battery management, resulting in the significant contribution to the sustainable progress of transportation electrification. This study provides a concise overview of the literature, offering insights into the current state, future prospects, and challenges in implementing ML techniques for battery health monitoring.
