NVH

HyperWorks for Automotive Noise and Vibration Analysis
Automotive Noise and Vibration Analysis involves some of the largest and most complex models being used for Finite Element Analysis. Models regularly involve millions of finite elements, with thousands of components and properties, along with the connections between those components.

Altair NVH Director is the most advanced true full-vehicle NVH solution, bringing benefits of highly sophisticated NVH simulation capabilities to NVH users:

  • Object-oriented assembly environment: enables users to manage subsystem representations, 3D display, FE entity ID numbering, connection properties and assembly definition in a modularized manner for ease of handling and debugging

  • Integrated solution: facilitates efficient execution of all aspects of the full-vehicle NVH process, including subsystem meshing and assembly, NVH event simulation loadcases and solutions, and problem diagnostics and optimization

  • Specialized NVH functionalities: simplified workflow for creating and managing lumped parameter model, complex mounts and joints needed for simulating suspension and driveline; acoustic cavity meshing for fluid structure interaction analysis; and creating coarse display mesh for simplified 3D display

  • RADIOSS solver: a next-generation finite element analysis (FEA) for linear and non-linear simulations, used to simulate structures, fluids, fluid-structure interaction, including subsystem model dynamics reduction to component mode synthesis (CMS) superelement and frequency response function (FRF) based representations.

  • Problem diagnostics and study: powerful post-processing utilities for understanding physical root causes of NVH problems, and identifying sensitive parameters through quick what-if studies

  • Optimization ready solutions for when you are ready to make the leap from simply solving a problem to simulation driven design

  • Latest simulation technologies: enhances users’ experience by leveraging browser, connector, data manager, process manager technologies


NVH Director, the first commercial software tool that makes full-vehicle NVH simulation possible in the most advanced and streamlined form, dramatically reduces the simulation cycle time, freeing CAE engineers to focus on optimizing product design and performance.
