Noise, vibration and harshness (NVH) simulation software from Bruel & Kjaer is now available to automotive designers as a module in Altair HyperWorks CAE design software. Automotive designers using Altair CAE software can now choose a module called Insight+, which enables them to listen to the sound a vehicle would make if it featured their virtual design.
This new Insight+ capability from Brüel & Kjær quickly processes CAE models into detailed sound models and allows designers to listen to them.
Because vehicle NVH characteristics affect people, subjective assessments are increasingly important to automotive designers. While data and graphs remain invaluable, virtual prototypes let designers observe and compare new component designs at a system level, which takes into account the entire vehicle and its interaction with the environment.
By enabling people to experience complex NVH data, such as source strengths and transfer functions, in a tactile manner, decisions can be made earlier in the development process with greater confidence.
During the development of vehicles, design teams often have NVH data from measurements on a real vehicle. The goal is to design new components and assess their effect on the vehicle’s NVH – before a physical prototype is made. With the Insight+ module, CAE designers can ‘play’ the sound of a completely virtual component that has been ‘inserted’ into otherwise real data, recorded on a vehicle.
