Powertrain testing

Our drivetrain testing test benches have been developed to test transmissions as an assembly, as part of a drivetrain, or as part of the entire vehicle. Independently of the customer’s specifications, ATESTEO conducts functional or endurance tests of transmissions and drivetrains. Combustion engines or electrical motors are used as a drive. All test benches are prepared to conduct tests on passenger or commercial vehicles. We offer our customers future security above all in the field of e-mobility. ATESTEO maintains many own test benches for testing electric motors, inverters, hybrid drives, and auxiliary electrical components, and for simulating battery systems as well.

NVH/acoustics

For testing acoustics and vibrations of vehicles, ATESTEO has at its disposal various test benches such as noise, vibration, and harshness (NVH) drivetrain test benches and an gear acoustic test bench ATE (anechoic test chamber for transmissions with engine torque pulsation simulation). In addition, we support our customers to develop torsional vibration dampers.

New NVH test benches starting in mid-2017: At our new NVH test benches, you can test your prototypes even more effectively for audible and perceptible vibrations of transmissions and drivetrains.

  • With 25 channels to measure sound pressure, sound power, and structure-borne sound.
  • Simulation of combustion engines and drivetrain.
  • Analyses of NVH phenomena such as transmission rattling and howling.
  • Suitable for all transmission types including AWD, along with all hybrid and electric drives up to 20,000 rpm.

Vehicle tests

Complementary to its test benches, ATESTEO offers its own test track for passenger and commercial vehicles. The proving grounds are concealed from view and suitable for PBN (pass-by noise) measurements. During test drives, we create situations in which the entire vehicle or its components are examined. In addition, we have chassis dynamometers to test the entire vehicle and measure fuel consumption. In our own cold chamber, the drivetrain can be calibrated to extreme climatic conditions to test cold starting and components.
