Noise Vibration & Harshness (NVH) Applications Available Through the Altair Partner Alliance
Best of Noise Vibration & Harshness (NVH) Applications From the Altair Alliance
AlphaCell by Matelys
Simulate the Vibro-Acoustic Response of Multi-Layer Trims Using the Complete and Accurate TMM/FTMM Solution
Based on an intuitive interface, AlphaCell features an extended material library, a project management for simulations, a customizable PDF report generation of the simulations, a data export/import for FE material cards. AlphaCell also computes the stationary thermal properties of multi-layer arrangement, possibly accounting for thermal bridges.
Enable Subjective Evaluation of Simulation Results by Coupling Insight+ with Altair's NVH Director
Insight+ analysis and playback allow you to calculate, listen to and modify individual noise and vibration contributions from your test data and/or CAE models in the full frequency range, bringing a realistic experience of NVH characteristics forward in the design process.
Vibration Control and Reduction for Structures and Systems
AdaptroSim for Altair supports the development of passive, adaptive, and active measures of vibration control and vibration reduction for structures and systems. AdaptroSim for Altair is available through an Altair Compose® and Altair Activate® library and interfaces with Altair® OptiStruct®.
Perform Analysis for Mid to High Frequency and Acoustic Simulations for Complex Structural Acoustic Systems
EFEA allows rapid evaluation of the vibration levels and the interior noise in complex systems. Design changes and the use of treatment configurations can be assessed for achieving the desired performance without an excessive increase in the weight of the system.
The hybrid finite element analysis (HFEA) extends the applicability of finite element models to higher frequencies for vibration and noise simulations. The method has been validated in the past in several automotive applications.
Calculation of Sound Radiation in Free Field from Vibrating Structures
AVL EXCITE™ Acoustics is a tool for the calculation of sound radiation in free field from vibrating structures such as engines and power units using the Wave Based Technique (WBT).
Coustyx is a state-of-the-art acoustic analysis software developed with funding from the National Science Foundation for computing Sound Fields. Coustyx uses the Fast Multipole Method (FMM) and advanced Boundary Element Method (BEM) formulations to yield fast, accurate solutions to acoustic field problems over a wide frequency range.
