DSD Simulation Method Reduces Late-Emerging NVH Issues in EVs

Drive System Design (DSD) has developed an innovative simulation method that highlights potential NVH issues of electric drive units (EDU) whilst the design is still model-based.

DSD has developed a system-level modelling approach using component and sub-system correlation tests to accurately simulate NVH behaviour. The company can accurately model anisotropic components and complex joints, which is critical to understanding how individual components interact at a system level. The approach has successfully been used on current development projects to identify NVH issues that would have otherwise been missed at this stage.

As an independent consultancy, DSD works with a range of OEMs and Tier 1 suppliers from different industries exposing it to a variety of technologies and applications. This has culminated in an extensive and ever-growing knowledge base, which is used to continually improve the accuracy of the model.
