Lei Huang, a sophomore mechanical engineering student from China, knew early in life that he wanted an American college experience where he could excel in academics and beyond. During his first year living in Iowa State residence halls he made many friends and improved his English. At the same time he established a stellar academic record.
In his second semester on campus, Lei learned about Providing Experiences in Research for Undergraduate Students in Engineering (PERUSE). He was offered a valuable opportunity to work under Dr. Jonathan Wickert, department chair of mechanical engineering, in the Vibration and Noise Control Laboratory.
Lei is excited about the research, which involves testing the vibration in blades of a wind turbine and tower. Efficiency calls for larger blades, but as the blades get bigger the vibration is also increased. Researching specifications and using SolidWorks software, Lei produced a scaled-down model of a wind turbine. The next step was to use the Stratasys prototyping and manufacturing system to build a three-dimensional prototype composed of production thermoplastics that would closely predict end-product performance. Lei found his freshman design courses helpful in executing this research. Building a small wind tunnel in which to place the prototype for the study of wind vibration is next on the agenda.
Research is a rich learning experience for Lei. He had no idea about the problems caused by vibrations before starting this research. He better understands the processes of engineering research. Each week Lei meets with the lab group where members take turns presenting their research. This fall Lei presented a PowerPoint presentation to his research group. He also presented a poster and responded to questions for the Mechanical Engineering Industry Advisory Council meeting. Lei meets on a weekly basis with Dr. Wickert. Lei is grateful for the time invested by Dr. Wickert in developing his research expertise, and for the PERUSE program that helped him find an undergraduate research position.
