Altair Embeds Brüel & Kjær Sound Simulation in CAE
Brüel Kjær’s NVH simulation expertise lets designers listen to alternative CAE models
DENMARK, - Brüel and Kjær noise, vibration and harshness (NVH) simulation software is now available to automotive designers as a module in Altair HyperWorks CAE design software.
David Mason, Vice President, Global Automotive at Altair, said: “Altair is thrilled to be adding Brüel and Kjær’s software to its NVH portfolio.”
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 NVHÂ - 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.
As David Mason says, “The powerful capability of Insight+ to evaluate NVH testing and simulation data together, especially listening to the result, will enhance our customers’ ability to make critical decisions earlier in the design process.”
NVH testing and CAE design have traditionally been separate domains but are increasingly coming together as more comprehensive simulations are used instead of physical prototyping. Integrating test data and CAE models, as in Insight+, helps unite the separate disciplines.
"We are very excited about our partnership with Altair,” said Alun Crewe, Vice President, Strategic Marketing at Brüel & Kjær. “CAE analysts, NVH evaluation teams and other decision makers, who may not be NVH experts, will be able to evaluate NVH design proposals at virtual prototype stage in the context of driving the final product. This enables improved, value-based decision-making, reduces the number of physical prototypes, ensures ‘right first time’ engineering and reduces time to market.”
Insight+ allows designers to experience NVH data subjectively, in fixed driving conditions. But this is just the entry point to Brüel & Kjær NVH simulation tools, where simulation data can be experienced in a more immersive context.
The next stage of the Brüel & Kjær simulation portfolio is the desktop NVH simulator. Designers and managers alike can drive vehicle models in a realistic, interactive environment using a steering wheel and pedals, letting them evaluate designs in free driving conditions.
