Vehicle NVH Prediction with virtual prototype assembly<\/figcaption><\/figure>\n\n\n\n

I’m an extremely curious person. When I start something, I’m already picturing the result: how it will look, feel like, how it will sound\u2026?<\/p>\n\n\n\n

We always aim for the best possible result, but in a complex scenario, where many parts must come together, it is hard to predict the outcome when all the building blocks are at their place. This complexity makes it hard to formulate realistic design targets for the subsystems early in the development cycle.<\/p>\n\n\n\n

It’s similar for every new product. Just take the example of a vehicle: probably you know how an engine, a tire, a suspension, etc., is performing as a component, but when you integrate everything into the vehicle, can you still perceive it as good?<\/p>\n\n\n\n

Should you wait to fully integrate all components to have a perception of a good or bad vehicle?<\/p>\n\n\n\n

Sometimes it’s not even possible: too many variants on the market, the increasing importance of controls, the advent of electrification and the modular platforms make it impossible to run all the necessary NVH tests within a reasonable timeframe and budget. Also, can OEMs still use the data at full vehicle level to cascade down to target setting at subsystem level and doing benchmarking with predecessor or even competitor vehicles? <\/p>\n\n\n\n

How can we overcome these challenges? System NVH performance prediction is the answer!<\/h2>\n\n\n\n

Need to know the impact of modifying the structural properties of the vehicle body or engine mounts on comfort, noise, and vibration? Want to evaluate the difference in NVH performance for different vehicle variants as early as possible? Or understand the influence of control changes on vehicle NVH performance? You can answer all these questions and more using the NVH prediction capabilities of Simcenter Testlab Virtual Prototype Assembly (VPA).<\/p>\n\n\n\n
