A complete NVH simulation solution
High-accuracy noise, vibration and harshness (NVH) analysis is crucial for meeting NVH targets and shortening the development and verification cycle. Balancing powertrain performance with quietness of the cabin interior, masking tire and wind noise to provide a superior quality of the ride are just a few examples of the challenges that eMobility brings.
The wide frequency spectrum where the vehicle must showcase excellent NVH performance requires engineers to adopt a variety of solutions and materials, each designed for a specific frequency range and noise source.
Hexagon offers an end-to-end solution for NVH with industry-standard tools that allow engineers to optimise the structural behaviour (vibrations), encapsulate noise sources (acoustic materials) and reduce the emission levels of the powertrain (gears and bearings).
Right the first time
Electrification brings several new challenges for the powertrain NVH, including a shift from low-frequency to high-frequency noise, new designs, more lightweight, stiff chassis and a greater need to balance NVH performance with efficiency. At the same time, automakers want to reduce development time, prototyping and testing, as well as understand powertrain sound quality from the end-user's perspective.
Providing fast, accurate solutions for engineering insight and optimisation, Hexagon’s advanced simulation capabilities are proven to work in the real world. Combining advanced capabilities with interfaces to the rest of your CAE ecosystem, Hexagon enables a “right first time” CAE-led solution for powertrain NVH design.
Evaluate full vehicle performance effortlessly
Evaluating full-vehicle NVH performance for the complete frequency spectrum can be challenging, especially when fast answers are required early in the design process. But it does not have to be.
Hexagon provides a complete solution that can:
- Solve large models faster
- Simplify complex model assembly
- Use machine learning to get insights in real-time
- Tackle high frequencies efficiently
- Optimise the trim package for performance and cost
- Compute airborne noise based on transmission loss data
- Accurately predict the effect of secondary noise sources such as tire noise and wind noise
And all within the context of the full vehicle.
Hexagon offers an end-to-end solution to full-vehicle NVH that can enable automakers to reduce prototyping, shorten the development cycle and produce lightweight vehicles with optimal NVH performance.
