Title of Speech: Control of Kinetic Energy Recovery Systems for Hybrid Electric Vehicles
Abstract: Hybrid Electric Vehicles (HEVs) are becoming increasingly popular as the world become more environmentally conscious. The primary advantage of hybrid electric vehicles is their extended travel range when compared to full electric vehicles. However, the efficiency of hybrid vehicles is limited by the ability of their small electrochemical batteries, intended only to store the energy recoverable from a typical braking cycle, to absorb large regenerative braking currents. Energy in excess of what the battery can safely absorb must be dissipated through the friction brakes of the vehicle. To address these problems, Kinetic Energy Recovery Systems (KERS) incorporates a mechanical flywheel energy storage system into HEVs to increase overall system efficiency, extend battery life, reduce the needed volume of batteries, and extend travel range. The work to be presented shows the design of a low-cost KERS system, using technology appropriate for consumer and commercial HEVs. A supervisory control system for directing the appropriate level of power to the vehicle, chemical batteries, or flywheel is described. A small demonstration vehicle using the KERS system as described was built and tested, and the results from the testing are presented.
Biography: Dennis Lieu is a Professor of Mechanical Engineering and former Associate Dean of the College of Engineering at UC Berkeley. He received his BS, MS and D.Eng. in Mechanical Engineering from UC Berkeley in 1977, 1978 and 1982, respectively. After working for six years as a design engineer in industry, he returned to his alma mater and has been a member of its faculty for 30 years. He is the author or co-author of numerous articles on permanent magnet motor design and engineering graphics education, and is the lead author of Visualization, Modeling, and Graphics for Engineering Design (Cengage Publishers). His research interests are in the design of electro-mechanical devices and the design of sports equipment. He is a recipient of the UC Berkeley Distinguished Teaching Award. In 2008, he was awarded the Orthogonal Medal for his contributions to engineering graphics education. In 2015, he received the Distinguished Service Award from the Engineering Design Graphics Division of the ASEE. Prof. Lieu is currently engaged in the development of design courseware associated with the new Jacobs Design Institute at UC Berkeley.
Title of Speech: Development of specialized engineering equipment
Commercial deployment of research output is a very daunting issue faced by most researchers. The strategy to commercialize market ready prototypes should start with preserving the “crown jewels”, the technology that is the basic premise of the innovation or the essence of what has been proven. Without changing the proven functionality, the parts surrounding the core technology and supporting systems would be designed or redesigned for the best manufacturability, cost, quality, and time-to-market while being integrated into an optimal product architecture.
The Centre of Advanced Manufacturing and Material Processing (AMMP Centre), University Malaya has been involved in numerous commercialization of research outputs and industry related projects from its inception in 2002. Several successful projects is presented as case studies to show its engineering development phases from concept ideas, modelling, lab prototypes, industrial redesign, commercial packaging and testing, scale up production and final sale and support services.
The talk will present the developmental journeys of these projects, highlighting the various stages in the process, such as in design conceptualization, prototyping, testing and commercial packaging. The products highlighted are, a modular Computer Numerically Control (CNC) lathe machine designed for the educational and Small & Medium Enterprises (SME) sectors, a specialized apparatus for the thermal testing of dental materials, an Minimum Quantity Lubrication (MQL) system for nano-lubrication during metal cutting and a powder Physical Vapour Deposition (PVD), a novel apparatus for the deposition of thin films from elemental powders.
Biography: Professor Ir Dr Mohd Hamdi bin Abd Shukor received his B.Eng. (Mechanical), with Honours from Imperial College London and his M.Sc. In Advanced Manufacturing Technology & System Management from University of Manchester Institute of Science & Technology (UMIST). His Doctoral study was in the field of thin film coating for biomedical applications for which he was conferred Dr. Eng by Kyoto University.
