Testing Equipment

Chassis Dynamometer

Despite development of new simulation software, vehicle chassis dynamometers are still necessary in determining vehicle performance. Increasingly complex vehicle technology and regulatory restrictions mandated by environmental protection bodies make optimized vehicle design necessary to meet a variety of vehicle applications.

The chassis dynamometer applies a load to a complete test vehicle. It comprises an integrated assembly of mechanical, electro-mechanical, and electrical/electronic sub-systems which function together to simulate actual road loads while the tested vehicle remains confined to the test facility. In addition to the vehicle performance information the dynamometer system provides during a test, specific engine performance characteristics can be monitored using instrumentation and diagnostic equipment connected to the test vehicle.

Water-brake Dynanometer Ideal for Wide Range of Testing Situations

Water-brake dynamometers are particularly well suited for both steady state and transient testing and are known for providing low inertia, durability and limited maintenance requirements. The turbulence and back pressure from the water within the dynamometer absorbs the vehicle's power. This braking action or load is developed by a rotor that directs the water against a stator that in turn redirects the water back against the rotor thereby opposing the motion of the rotor.

The Taylor TD-36 tandem axle chassis dynamometer is the equipment of choice as an integral part of WESTEST’s Vehicle Performance Center.

Features include:

  • Capable of absorbing 1100 horsepower starting at a speed of 72 kilometres per hour (45 miles per hour). Maximum speed of operation is 160 kilometers per hour (100 miles per hour).
  • 128 channel vehicle data collection station
  • Host computer system preloaded with dynamometer control software
  • Durability and stability with structural steel frame housing four, 914mm (36-inch) dynamically balanced rollers
  • Rear tandem axle spreads of 1.2 to 1.5m (46 to 60 inch) can be accommodated
  • Vehicle restraint kit.

The Dynamometer Can Perform a Number of Value-added Tests to Assess Vehicle Performance While Operating Under Load, Including:

  • Vehicle Heating & Cooling Systems
  • Drivetrain component evaluation, performance and durability
  • Tire Testing
  • Track Lap Simulation
  • Road Grade Simulation
  • Trailer Towing Simulation
  • Fuel Efficiency
  • Auxiliary Components
  • Failure Analysis.

Benefits to the vehicle manufacturing industry include:

  • Providing a load-control device for running vehicle tests
  • Providing a shared resource for vehicle manufacturers that would be cost prohibitive for individual companies to provide
  • Combining the chassis dynamometer with the Vehicle Performance Centre's computer-controlled air-exchange system allows testing under controlled ambient conditions to comply with generally accepted evaluation protocols
  • Testing to verify bid compliance to satisfy contractual obligations
  • Testing to statistically verify baseline performance conditions for quality control compliance.
