Determining the service life of individual components or assemblies of a powertrain right up to entire transmissions can be achieved on the test bench in a short period of time with a specified excessive stress. The resulting pattern of damage should represent the service life of the vehicle similarly to customer conditions. ATESTEO is able to conduct appropriate inspection procedures and tests on its own test benches, both with pure electrics and using the combustion engine. Virtually stationary states and dynamic operations are simulated during the test cycle. The test benches can be adapted to the requirements of passenger cars, commercial vehicles, moving working trains, or high-speed trains.
