ROTATION & TORQUE

ROTATING & TORQUE MEASUREMENTS

MINATURE DATA RECORDERS ELIMINATE NEED FOR SLIP RINGS

The Challenge: 

• Collecting data on rotating test articles like drive shafts or rotors
• The University of Florida Formula SAE needed to collect transient load data to calculate fatigue-life of drivetrain and suspension components, plus tuning of spring and dampers to improve acceleration performance
• Engine dynomometer data could not replicate impact loading and transient conditions
• Cost and maintenance of expensive slip rings
• Power and triggering concerns

The Solution:

• An ultra-small DTS data acquisition system was attached directly to the drive shaft
• The University of Florida selected SLICE NANO due to its small size and 500 g shock rating
• To protect it from track debris, the DAS was mounted to the drive shaft in an enclosure
• Positioning DAS near the sensors eliminates long cable runs, improves data quality & reduces noise
• Low power, three 9V batteries were wired in parallel and attached to the rotating shaft
• Store in place reliability, data writes directly to flash memory
• Trusted complete solution provider and industry expert in automotive safety testing
• See University of Florida Formula SAE White Paper for more details and test data
