NVH, Drivetrain and Chassis

NVH, Drivetrain and Chassis Testing Solutions for Automotive Performance

When it comes to vehicle development, achieving the right balance between performance, comfort, and noise control is critical. Noise, Vibration, and Harshness (NVH) testing is a key part of this process, it helps manufacturers evaluate how multiple components of a vehicle work together to create a smooth and comfortable driving experience. At AcSoft, we provide you with the tools and expertise to guarantee your drivetrain and chassis systems are optimised to the best possible performance.

What is NVH Testing in the Automotive Industry?

NVH testing plays a very important role when it comes to the automotive industry, it assess how noise, vibrations and harshness can affect the overall driving experience of vehicles. By evaluating how different parts of a vehicle interact with one another, we can identify which areas are contributing to any unwanted noise or vibrations. Our NVH testing solutions give manufacturers the important information that they need to improve and refine their designs, which further helps them with meeting regulatory standards and inevitably customer expectations for ride quality and comfort.

How Does the Drivetrain Contribute to a Vehicles Noise & Vibration?

The drivetrain, which includes key components like the engine, transmission and axles, can often be the source of a vehicles noise and vibration.
If it is not fine-tuned, these components can create unwanted noise frequencies and vibrations that are transferred throughout the vehicle. AcSoft’s solutions aid engineers when it comes the analysis and measurement of these vibrations, supplying them with the insights needed to adjust and optimise drivetrain performance. Our real-time feedback allows manufacturers to address potential issues early in the design process.

How Can the Chassis Affect The Overall Vehicles NVH?

The chassis is the foundation of any vehicle, it provides the structure that supports vital components such as the drivetrain and suspension. It plays a very important role in the vehicles NVH performance. A well-designed chassis can significantly reduce noise transmission and absorb vibrations more effectively, inevitably leading to a smoother and quieter experience. However, vibrations from things such as the suspension system itself, engine mounts and even the road surface can all still contribute to the ride quality and cabin noise. Here at AcSoft, we collaborate with vehicle manufacturers to ensure that chassis designs are optimised for both the vehicle’s performance and comfort as we utilise advanced testing methods to asses and refine these systems.

What are the Key NVH Testing Methods Used in the Automotive Industry?

Within the automotive industry there are a range of NVH testing methods commonly used. These typically include things such as, frequency and vibration analysis, and acoustic measuring. By monitoring the intensity of the frequencies outputted by the noise and vibrations, engineers can determine how these factors affect vehicle performance. We at AcSoft utilise state-of-the-art equipment and software to perform these tests, which allow accurate results that guide the design process and lead to better performance in manufacturers vehicles.

What Role Do Accelerometers and Microphones Play in Vehicle Testing

During the NVH testing phase, we rely on specialised instruments and tools such as accelerometers and microphones to monitor the noise and vibration levels. The accelerometers provide data on the acceleration of components which helps track the vibration levels in real time. The microphones help us to capture the sound frequencies produced by components like the drivetrain and chassis. Combined, these tools give us a comprehensive view on how the vibrations and noise are impacting the vehicles performance, which in turn helps the engineers make more informed decisions when it comes to design changes to the vehicles.

How Does a Chassis Dynamometer Contribute to NVH Testing?

A chassis dynamometer is a crucial tool used for simulation the real-world driving conditions during NVH testing. It measures how the drivetrain and chassis perform under various loads and driving scenarios, allowing engineers to identify and address any potential NVH issues that might not be obvious under more normal testing conditions
