As a leading provider of testing equipment and high-tech engineering services, we specialize in single components, powertrains, and complete propulsion systems. Our innovative, user-oriented solutions are tailored to the specific needs of our customers' units under test (UUT). We are committed to meeting the strict acoustic standards required in modern NVH testing, ensuring that all systems meet agreed-upon NVH targets. Each component is carefully tuned, and the entire system is validated through a comprehensive acceptance analysis, guaranteeing optimal performance.
Our advanced NVH test systems are designed to support all UUT variants, enabling precise validation of e-motors. We provide highly efficient, fast, and sustainable solutions to tackle NVH challenges, ensuring optimal testing conditions for reliable results.
A key advantage is the specially engineered load unit and acoustic chamber, which allow for ultra-low noise measurements even at high speeds. This minimizes interference with the acoustic free-field conditions of the laboratory, ensuring highly accurate data. Additionally, our test facility offers seamless integration into existing infrastructures and is available as a flexible, mobile containerized solution.
Key Features:
- Ultra-Silent Design: Achieve minimal overall noise levels in the test cell, with noise as low as 50 dBA at 20,000 rpm, ensuring precise and quiet testing conditions.
- Containerized Solution: Our fully assembled, pre-commissioned testbed comes ready for immediate use, significantly reducing onsite setup activities and ensuring a faster, more efficient deployment process.
Premium Setup
Our premium test setup is designed for the development of ultra-silent e-motors, ensuring maximum measurement accuracy in an optimized testing environment. With an ultra-low background noise level of less than 50 dB(A), it provides outstanding signal-to-noise ratio (SNR) for reliable Class 1 measurements. The innovative decoupling concept ensures that the UUT remains completely independent of external vibrations, delivering precise and undistorted acoustic data. Additionally, the system offers full power, torque, and speed performance while seamlessly integrating into the AVL toolchain, enabling efficient development and validation processes.
Precision Setup
Our precision test system ensures full compliance with ISO 3745 by enabling an optimized microphone setup for accurate acoustic measurements. The complete microphone hemisphere allows precise detection of single-spot noise phenomena without interference from mechanical surfaces. An innovative decoupling concept ensures that the UUT remains completely independent of external vibrations, delivering reliable and undistorted results. Additionally, the system provides full power, torque, and speed performance while seamlessly integrating into the AVL toolchain for efficient testing and validation.
Efficiency Setup
The efficiency test setup enables a fast and cost-effective upgrade of existing anechoic chambers into high-performance e-motor NVH test systems. Optimized dyno enclosure design minimizes acoustic reflections, ensuring precise measurements. The flexible setup allows easy repositioning of the test system for different UUTs, including e-motors, e-axles, and powertrains. With full power, torque, and speed performance, along with seamless integration into the AVL toolchain, this solution provides the ideal balance between efficiency and NVH performance in modernized testbeds.
