Project Type: Driveline Test System
Customer: BorgWarner Automotive, Auburn Hills, MI
Dynamometer: Dual 300Hp AccuDyne AC Dynamometers
Control System: DynoLAB with remote I/O
Other Equipment: High-speed data logging system, CAN communications interface
SAKOR designed this system for loaded testing of transfer cases, ITM’s, and other torque transfer devices. The system is specially configured so each dynamometer can run independently as a spin stand with its own DynoLAB controller, or both dynamometers can be controlled by one DynoLAB system to provide an integrated drive/load testing system. The test system also can automatically shift the device under test directly, or via CAN interface. The dual dynamometers have been engineered with a common regenerative front end that is extremely power efficient, recapturing up to 90% of absorbed power. This also allows the dynamometers to be completely air-cooled, eliminating the need to provide fluid-cooling capacity.
