Combining renewable energy and design-for-manufacturing research in an undergraduate research project

Abstract

Northern Arizona University's (NAU) College of Engineering and Technology (CET) is integrating the traditional topics involved in design-for-manufacturing research and education with the reemerging field of renewable energy. In particular, student research projects were conducted for the optimization of injection molding process parameters for a small wind turbine blade to produce the fewest manufacturing defects. The defect of interest was warp-the level of part distortion predicted after the molding process. Deviation from the designed turbine blade geometry degrades the predicted energy output for the system, thus inspiring this research. The research activities involved manufacturing simulation and design-of-experiments (DOE) in order to create and examine a mathematical response surface. Presented herein is a background to the NAU sustainable energy solutions research and education activities, the particular problem formulation for the undergraduate research, the educational approach necessary to support the undergraduate researchers, the implementation of the research activities, and the project outcomes.
