NVH & Acoustics

NVH & Acoustics for Automotive Performance

The NVH and acoustic performance of a vehicle strongly impacts the driving experience and hence the perception of quality. Impacted by regulations and low-emission and zero-emission strategies, car manufacturers and suppliers seek solutions to design for optimal NVH comfort to adhere to their brand identity.

The integrated NVH and Acoustic solutions of Siemens Digital Industries Software are designed for combining simulation and test. They enable you to analyze the root cause of noise and vibration problems, optimize vehicles to improve brand image, and increase the perception of quality. Our tools and services help you design correctly from the start and prevent costly redesign later in the vehicle development cycle.

A vehicle’s noise and vibration behavior primarily influences comfort and the perception of quality. Excessive or unpleasant vibrations and sound affects the product’s brand image. The pressure on NVH engineering is constantly increasing. While legislation and regulation tightens, the automotive industry is confronted with a renewed need to address particular NVH challenges on component, subsystem, and full-vehicle level.

To design for premium NVH and acoustic quality, an integrated approach is required. Whether dealing with interior or exterior acoustics, intake or exhaust noise, engine acoustics, brake noise, noises from auxiliaries such as HVAC, batteries or inverters, or noise related to system integration, Siemens Digital Industries Software provides solutions for all stages of the development process. By combining simulation and test, our solutions help you to gain insights in how to reduce noise and vibrations, assess systems interactions and their influence on other performances such as fuel consumption, passenger comfort, and drivability, while striking an excellent balance between cost-efficiency, weight, and performance.

Lösungsfunktionen

Modal testing

Die Erzielung genauer Frequency Response Functions (FRFs) ist der Ausgangspunkt für zuverlässige NVH-Tests und -Analysen, und zwar in jeder Situation, wie z. B. bei der Durchführung einer Modalanalyse, der Fehlerbehebung bei Schwingungsproblemen oder der Durchführung einer Transferpfadanalyse. Verlassen Sie sich auf unsere speziellen Lösungen für Modalhammer- und Shakertests sowie auf unsere große Auswahl an Schwingungserregern, um Ihre Prüfszenarien durchzuführen und schnell und effizient Daten in höchster Qualität zu erhalten.

Operational NVH Testing

Quickly and reliably assess noise and vibration in operational conditions and instantly validate measurements on the test track or road.

Road Noise Simulation

Reduce road noise in the passenger compartment by predicting the dominant path or component early in the development phase.

Road Noise Testing

Lower road noise levels following a transfer path analysis (TPA) approach. Decompose road noise into independent components and investigate each individual noise source.

Sound Quality Acoustic Simulation

Minimize noise and optimize sound quality by analyzing and simulating interior and exterior acoustic noise.

Sound Quality Testing

Evaluate acoustic quality and design the perfect sound. Assess sound and acoustic quality using psychoacoustic metrics with real-time and offline access to results.

Vehicle Integration & Attribute Balancing

Integrate (sub)systems and keep performances. Balance and optimize conflicting requirements for NVH, fuel economy and drivability to ensure the desired driver experience.
