Manufacturers want to reduce the risk of encountering e-drive NVH issues late in the design process. But, optimizing e-drive NVH to create a sound that fits your brand image, is challenging. Where to start? Let’s start here. <\/em><\/p>\n\n\n\n

Electric vehicle sales are booming<\/h2>\n\n\n\n

The electric vehicle revolution is well underway. According to BloombergNEF\u2019s recent report,<\/a> there are currently around 12 million passenger electric vehicles and around one million commercial electric vehicles on the road globally. And this is expected to surge. The growth of passenger electric vehicles is projected to rise from 3.1 million in 2020 to 14 million in 2025.<\/p>\n\n\n\n

But as demand grows, and many markets move towards ending the sale of combustion engine vehicles, expectations are increasing too.<\/p>\n\n\n

What\u2019s that noise?<\/h2>\n\n\n\n

As you might know, at Simcenter, we adopt a people-centric approach to the NVH performance engineering<\/a> of electric cars. When engineering the electric drive, a common complaint is the high-frequency tonal noise of the electric motor and gearbox.<\/p>\n\n\n\n

To satisfy their customers, manufacturers need to address these E-Drive NVH issues to give the best results in terms of performance, customer comfort, and satisfaction.<\/p>\n\n\n\n

Simple, right?<\/p>\n\n\n\n

Not really, given the complexity of the motors and the number of different models that are produced every year. NVH performance analysis has often been left to the end of vehicle development. This makes it difficult to make significant design changes to improve the sounds generated. That\u2019s understandable, given that you need a completed motor to evaluate its NVH performance. But that’s not what customers want, they just want their cars to sound better.<\/p>\n\n\n\n

Simulation for success<\/h4>\n\n\n\n

This is why virtual simulations are so valuable in modern vehicle development. It is exactly the kind of challenge that Simcenter was designed to overcome. Alessandro Lepore<\/a>, Business Development Manager for Simcenter Engineering Services<\/a> Solutions recently ran a webinar to show how Simcenter can front-load NVH evaluation in the development cycle to allow manufacturers to build a better product whilst keeping within their cost and time budgets.<\/p>\n\n\n\n
