Road Simulators/Mileage Accumulation Dynamometers
Office of Automotive Engineering
One of the four newly installed road simulators is configured to support four-wheel drive vehicles and supports hybrid vehicle testing under real-world conditions.
Using 24 road simulators, Southwest Research Institute (SwRI) conducts rapid, cost-effective, round-the-clock mileage accumulation at speeds up to 100 miles per hour. These chassis dynamometers accommodate most cars and light trucks up to 7,000 pounds, conducting any transient or steady-state driving cycle.
Of the 24 road simulators, one dyno offers four-wheel-drive capabilities and supports hybrid vehicle testing under real-world conditions. Four newly installed dynos have temperature- and humidity-controlled engine inlet air to ensure consistent operating conditions year-round. An additional high performance dyno is capable of supporting vehicles up to 400 horsepower.
SwRI evaluates durability and performance of automotive fluids, fuels, components and emission control systems. Features include:
- Transient and steady-state driving cycles
- Controlled and repeatable tests
- No downtime for adverse weather
- Side-by-side component comparisons
- Efficient multiple component testing
- Safe operation
- Convenient and real-time access to test data
- Ability to test prototype systems not yet roadworthy
