Improving the noise performance of EVs is essential. Designers and engineers typically use CAE tools such as Multibody Dynamics (MBD), Finite Element Analysis (FEA) and Multi-Domain Simulation tools to develop quieter products.

The overall objective is to simulate the dynamics of systems to identify and solve noise problems in simulation, ahead of prototyping and manufacturing. In effect design decisions can be made to avoid noise issues earlier, rather than later after they have occurred; helping you to work smarter and faster at reduced costs.

Romax offers leading CAE software products which offers a whole-system approach for design and analysis of NVH, efficiency and durability.

The latest development of RomaxDESIGNER R17 EV technology sees the release of a new Electrical Machine modeller, including an NVH analysis tool that interfaces directly with electromagnetic FEA.

This new software capability enables NVH analysis of a complete electro-mechanical drivetrain. It applies excitations from both gears (transmission error) and electrical machine (torque ripple, radial forces) and calculates the response of a full system model; including transmission, electrical machine and housing. Users are able to capture electro-mechanical NVH interactions in the early development stages and prevent problems from the start, therefore targeting a Right First Time™ solution.
