Experimentation and Laboratory-Oriented Studies
XXXXX University’s Mechanical Engineering program has seen frequent requests in surveys from graduating seniors and alumni to focus on hands-on experience in the undergraduate program. Along with that, there has also been a focus on participating in competitions such as Shell-Eco Marathon by senior for their capstone project. An opportunity arose to address both the issues by building an engine/chassis dynamometer.
A funding request has been granted by a robotics company paving the way for design and build of an engine/chassis dynamometer. The dynamometer, in its first iteration cost about $12,000 but a revised design costs around $8,000.
The dynamometer has been designed for Shell Eco Marathon competition but has found in uses in multiple projects over the past year, including a summer toboggan redesign for a local state park. The dynamometer is being used in courses such as senior design, system dynamics and controls, and mechanics of machinery, mostly to teach concepts such as energy accounting, gear/drive trains.
The design of the dynamometer and all the components are presented in this paper. The cost of each component is also presented along with suggestions to reduce cost for more cost-effective designs. It is hoped that this design will results in undergraduate institutions building dynamometers for use in their engineering programs, and even improve the design to make it more cost-effective.
