With extensive experience in NVH powertrain test systems, AVL delivers high-precision acoustic environments for electric powertrains. The simulation-optimized design minimizes sound reflections and ensures reproducible, high-quality NVH measurements at full system level. Integrated e-axle configurations as well as complete electric drive units can be validated under controlled laboratory conditions.
The test systems are equipped with modular load units that enable flexible adaptation to different powertrain sizes and performance classes. Hinged acoustic enclosures provide easy access for maintenance and help maintain a highly controlled measurement environment, ensuring operational efficiency and long-term reliability.
NVH Testing for Light-Duty
The AVL Powertrain TS™ NVH Light-Duty system offers a highly precise acoustic testing environment for investigating the NVH of modern powertrain architectures. This modular platform supports a wide range of applications, including individual components, such as gearboxes and e-motors, as well as integrated subsystems, such as e-axles and complete electric drive units. Its simulation-optimized shaft system and carefully engineered load units minimize sound reflections and structural excitation within the NVH chamber. These features enable exceptionally low background noise levels and excellent signal-to-noise ratios for precise acoustic measurements.
Thanks to its scalable configuration and unified measurement environment, the system ensures consistent and comparable NVH data throughout the entire development process, from component validation to full powertrain optimization. This allows engineers to identify tonal, high-frequency, and transient NVH phenomena while maintaining efficient and reproducible testing conditions.
NVH Testing for Heavy-Duty
The AVL Powertrain TS™ NVH Heavy-Duty system is designed to meet the demanding acoustic requirements of modern commercial vehicle powertrains. Its scalable NVH architecture enables the precise analysis of the acoustics and vibrations of high-torque propulsion systems, including internal combustion, hybrid and fully electric heavy-duty drivetrains. Acoustically optimized shaft systems, direct-driven heavy-duty dynamometers, and carefully engineered NVH components minimize acoustic interference within the test environment. This enables highly accurate measurements across a wide frequency range.
The flexible test cell configuration supports diverse unit-under-test layouts and realistic powertrain operation under high-load conditions. This allows engineers to reproduce critical operating scenarios and evaluate NVH behavior, achieving consistent, high-quality measurement results throughout the entire heavy-duty powertrain development process while supporting efficient and reliable validation workflows.
Optimized Space Requirements
Extremely low-noise performance as well as optimized shape and surface of the test equipment, for a minimum space requirement in the NVH chamber.
Adaptability to Various Propulsion Systems
Flexible and variable design for fast adaptation to different propulsion systems without compromising NVH performance.
High Performance
High torque capability with precise torque control.
Efficient Assembly and Replacement
Easy, fast assembly and replacement of UUTs for minimal downtime and high test efficiency.
Simulation Based In-house Design
AVL’s simulation-driven in-house design ensures ultra-low noise structures, precise dynamic behavior, and high NVH fidelity.
Low Noise Intermediate Bearings
The load system’s intermediate bearings are specifically designed for NVH applications to ensure smooth operation with low noise and vibration levels. This ensures the best possible focus on the test object.
Infinitely Variable Adaption Systems
Both track width and wheelbase can be adjusted in infinitely variable increments. This ensures perfectly repeatable mounting conditions for the UUT.
Quick Setup Time for Reduce Down Time
In addition to the focus on NVH performance, great emphasis is placed on ease of use of the test system. This reduces testbeds downtime and optimizes productivity.
NVH is not only about improving noise on vehicles and powertrains, much more it’s about setting up a brand sound, inspiring the passengers of modern cars during their ride. With our NVH test systems and solutions we provide a high class development platform for sound development and drive the pleasure of tomorrow’s mobility.”
