Speech Title: Health Assessment, Fault Diagnosis and Fault-tolerance Control for Aircraft Control System

Abstract: According to the control command of the pilot or the autopilot, the aircraft control system drives the aircraft rudder through the servo actuator to realize the aircraft attitude and flight trajectory control. It can be seen that the healthy service of the aircraft control system directly affects the flight safety and is a very critical airborne system. In order to realize the highly reliable and healthy service of the aircraft control system, the health status assessment and remaining useful life prediction of the key components of the aircraft control system, the key technology of fault diagnosis for the airborne hydraulic system, and the high safety hierarchical active fault-tolerance control strategy were carried out to effectively improve the healthy service capability of the aircraft control system.

Speech Title: Investigation of material properties of additively manufactured high‑impact polystyrene 

This study aims to investigate the tensile strength (TS) of FFF-printed high-impact polystyrene (HIPS) via devising a systematic testing and analysis framework, which combines experimental testing, representative volume element (RVE)-finite element method (FEM), rule of mixture (ROM), and artificial neural networks (ANN). HIPS samples are fabricated using FFF considering the variations of infill density, layer thickness, nozzle temperature, raster angle, and build orientation, and tested with standard tensile testing. The rule of mixtures (ROM) and its modified version (MROM) are employed to calculate the TS of longitudinally and transversely built samples at various infill densities, respectively, while an ANN model is constructed to investigate the effect of material anisotropy precisely. The optimal ANN architecture is built with five hidden layers with the number of neurons in each layer as 44, 82, 169, 362, and 50. Although both MROM and ANN perform well on the validation set, ANN exhibits superior accuracy with only a maximum error of 0.13% for training set and 11% for validation set. The combination of the RVE-FEM, MROM, and ANN approaches can significantly improve the FFF printing process of polymers for optimisation.

Speech Title: The Application of Carbon Fiber in Solar Car Body and Chassis Design

Abstract: In today's automotive industry, energy conservation and environmental protection have become the core themes of its development. The development of new energy vehicles also faces the crucial issue of lightweighting. This study focuses on the field of solar-powered vehicles and conducts in-depth research on carbon fiber design technology. Starting from the perspective of material selection, suitable carbon fiber materials are carefully screened. In the design stage, innovative and reasonable structural designs are carried out. In terms of the process, the processing technology of carbon fiber is optimized to ensure quality and performance. And through a strict testing process, the achievements of the design and process are evaluated. Based on the above research, several solar-powered racing cars have been successfully developed. Verified by practice, after applying the carbon fiber design technology, these solar-powered racing cars have achieved significant weight reduction, effectively reduced energy consumption, and improved energy utilization efficiency, showing outstanding performance in energy conservation. It provides important technical support and practical experience for the development of solar-powered vehicles and also offers useful references for the lightweight development of new energy vehicles.
