The purpose of this project was to design and develop a coupling device for use in noise, vibrations and harshness testing of drivetrains between a dynamometer motor and vehicle driveline. The system was designed to work with speeds up to 5000 RPM and torques up to 600 Nm. The coupler allows for adjustment of the apparent mass and the stiffness of the system. The project was sponsored by American Axle and Manufacturing (AAM) with Giovanni Rinaldi and Glen Steyer coordinating design requirements and specifications. Bill Braun joined the project during the winter. Lake Superior State University is also a stakeholder.

Major goals of the project included developing internal noise and mechanical performance specifications for the coupling device, such as tunable ranges of stiffness and inertia, and any balancing, alignment, torque and speed requirements. Multiple designs were developed and the most suitable was selected after a review with the AAM staff. Detailed design and analysis was performed leading to fabrication, installation and performance validation. The upgraded test stand permits the realistic testing and validation of the tested drivetrains in the absence of the rest of the vehichle machinery.

Fourth Place

“Pick-up Trucks and Aerodynamic Drag CFD Analysis” Presentation by senior Robert Camp based on research work done with Dr. Mokhtar during summer 2008.

An engineer, like all professionals, must possess a well-developed ability to communicate, both orally and in writing. This competition is designed to emphasize the value of an ability to deliver oral presentations.
