Dynamics & Vibration Engineering

The targeted control of vibrations and noise is now a decisive success factor for innovative products and systems. Whether in the initial design or during series acceptance testing, we use modern methods of vibration analysis and NVH optimization to ensure that comfort, safety, and reliability are taken into account from the outset and are guaranteed right through to operation.

Our range of research and development services for comprehensive assessment and optimization of dynamic behavior

We support you from the design phase through to the utilization phase in reliably evaluating and specifically improving the vibration behavior of components and systems under realistic operating conditions. In addition to analyzing and evaluating dynamic behavior, we develop and implement customized solutions for reducing vibration and noise (NVH) in various applications. This provides your engineering teams with a reliable basis for design decisions, enabling them to increase comfort, safety, and durability and efficiently meet approval and operational requirements.

Specifically, the range of services includes:

• Support in system requirements analysis and in the design phase for vibration-optimized assemblies and systems – so that comfort and reliability are considered right already in the design stage.
• Testing and evaluation of the vibration behavior of components and systems under realistic operating conditions, among other things, for early validation of design decisions and specifications as well as for later validation in operation.
• Development and implementation of solutions for vibration and noise reduction (NVH) for various applications.
• Analysis of mechanical vibrations and vibroacoustic radiation from components to the entire system, both during development and in ongoing operation.
• Experimental and numerical system analyses to identify dynamic effects at an early stage and optimize them in a targeted manner.
• Optimization of assemblies and systems in terms of vibration behavior, comfort, and noise.
• Special expertise in rotating components: evaluation of dynamic behavior and validation under realistic loads (e.g., wheel head systems).
• Validation in test facilities using reproducible measurement and evaluation methods, which are used both for concept development as well as for concept and final product validation.

Our research focus areas for virtual, hybrid, and data-based NVH development

In order to better control vibration phenomena and NVH challenges in increasingly complex systems or to eliminate them directly in the design phase, we develop innovative methods for virtual design planning, component validation, hybrid analysis strategies, and data-based NVH optimization. Our research specifically addresses open questions in the modeling, validation, and prediction of dynamic system behavior—especially under variable loads and in new fields of application.

Our research topics in detail: 

• Development of design routines for creating vibration-reduced assemblies and systems as a tool for avoiding vibration problems at the design stage and facilitating subsequent verification.
• Virtual DoE and hybrid testing strategies for vibration fatigue under variable load collectives for early evaluation and optimization of concepts and system designs
• Digital twins with virtual sensor technology and predictive health monitoring to derive models for the description of vibration-induced degradation and remaining fatigue life and to determine specifications as a basis for the development of monitoring strategies that enable targeted condition monitoring during operation.
• Data/model-based NVH optimization for the validation and optimization of NVH properties – from initial simulation to final validation.
