An advanced-level course in the purpose, construction and operation of the automotive chassis dynamometer. Demonstrates how to conduct vehicle tests of horsepower and torque, and covers setup of various sensor types and adaptation. Including how to correctly place and secure a vehicle on the dynamometer, how to instrument the vehicle, how to set up and run tests on the vehicle, how to log data, and how to interpret that data. Successful completion of this course will prepare the student for working in the field using dynamometers for OEM manufacturers and 3rd party R&D suppliers.
