The proposed collaborative research and development project, between the University of Waterloo and Smarter Alloys Inc., aims to bridge the gap between shape memory alloy (SMA) research and their implementation in automotive applications. In past research and development initiatives, Smarter Alloys Inc. showed that their novel multiple memory material (MMM) SMA processing technology overcame design challenges that previously retarded the application of SMA actuators in the automotive industry. In this project remaining challenges will be addressed such as, developing a robust control system for MMM processed SMA actuators, processing high phase transformation temperature NiTi alloys, and improving cyclic performance. The successful completion of this project will result in a working underhood SMA automotive belt tensioner prototype, demonstrating enhanced performance provided by the MMM technology. The engineering knowledge and expertise developed in this project will be immediately transferable to other automotive applications and even different industries such as, aerospace, medical, and micro-electronics industries who already utilize traditional SMA technologies. The successful execution of this program will not only provide valuable fundamental insight into manufacturing and controlling SMA actuators, but will also serve as a platform for the development of innovative technologies and for training highly qualified personnel (HQP) in the rapidly expanding field of smart materials. This research will, therefore, provide a significant Canadian contribution to the smart materials industry. Processing protocol and SMA materials science developed in this work will provide competitive advantage to the automotive and many other industries currently utilizing SMA technologies. The knowledge, HQP, and engineering know-how gained through this proposed work are essential in the advancement of the smart materials field and to increase flexibility in the design of innovative SMA devices.
