Dynamometer software handles brake testing

Link Engineering's Dual-by-Wire technology for brake test dynamometers permits dual-ended brake testing with nothing but electronic connections between dynamometers. It allows two single-ended dynamometers to be connected electronically to create a twin dynamometer and eliminates the need for a shaft connection between the two. The company's ProLink software handles inertia simulation and digital speed control to achieve the tight speed correlation necessary between the two dynamometers. The software enables a computer on one of the dynamometers to have overall control over both machines and to collect test data. The second machine's computer works to match the commands of the master computer. The brake systems can be combined to simulate actual vehicle arrangement or can be operated independently.
