The Southwest Research Institute (SwRI) has announced that its engineers have developed a test apparatus capable of simulating vehicle powertrain operations in the laboratory.

The apparatus uses hardware-in-the-loop technology and a software-controlled simulator to determine how a powertrain or related component would perform if it were integrated into a vehicle. SwRI said that this test system simulates the operation of a transmission under a wide range of real-world conditions. Similar test systems can be developed to test engines, electric motors, hybrid-vehicle battery packs, and other equipment under a variety of road and environmental conditions.

SwRI engineers further explained that the apparatus has the capability to simulate such real-world conditions as stop-and-go traffic, roll and grade angle, heat rejection, aerodynamic drag, varying temperatures, and other parameters.

The equipment and test cell were developed as part of a program funded by General Motors Corp. to test transmissions in the laboratory using an electric motor to simulate an internal combustion engine.
