混合NVH建模
Virtual prototypes save time and costs during development, and a sensible combination of simulation and testing further increases the savings effects and the accuracy of the results.
However, it is crucial to choose the optimal approach depending on the task and data availability (to build virtual prototypes), methods (to model certain physical phenomena), and physical prototypes.
HEAD acoustics can show you how to succeed in this endeavor, even considering human perception and psychoacoustic effects: Leap from simply imagining the acoustic properties of your future product to analyzing predicted human perception using a hybrid NVH modeling approach and psychoacoustic analysis. You can even listen to the results and experience your product long before it exists as a prototype.
Let's look at our real-world e-bike case study for a tangible example of the advantages of hybrid NVH modeling and psychoacoustic analysis. Here, a combined method of measurement and numerical simulation was used to predict and analyze Noise, Vibration, and Harshness (NVH) characteristics, meeting all the above requirements.
