Predict noise and vibration and perform systematic validation
LMS Virtual.Lab Noise & Vibration helps to analyze, refine and optimize the noise and vibration of a system under development, from the component- up to the system-level. LMS Virtual.Lab Correlation allows engineers to validate and further improve simulation models.
• Cascade system targets down to component targets • Integrate test information in simulation models for more efficient and accurate predictions • Analyze critical noise and vibration contributors and identify optimal design modifications • Refine noise and vibration performance before building the first prototype efficiently • Compare and validate FE models based on test data
LMS Virtual.Lab combines all the necessary tools to create system-level hybrid (combining FE and Test) models, build realistic load cases and simulate noise and vibration responses. It includes a wide range of visualization and analysis tools to explore noise and vibration performance and accurately pinpoint the most critical contributors. User-friendly tools enable engineers to quickly perform design modifications and assess the effect on the noise and vibration performance in minutes.
LMS Virtual.Lab Noise & Vibration and Correlation offers direct access to standard FE and test data including a unique export to LMS Test.Lab. It allows to quickly compare and validate FE models to test data and identify possible modeling errors to systematically improve existing simulation models.
LMS Virtual.Lab Noise & Vibration and Correlation Rev11 Always innovative
Premium NVH structural FEM solver A comprehensive FEM solver included in the NVH product portfolio supports the NVH hybrid engineering process. Test components (e.g. from LMS Test.Lab) can be coupled to FE-based components, calculated through the newly integrated NVH FEM solver. The element library supported in this solver is comprehensive, including 1D, 2D and 3D elements made of isotropic, orthotropic, anisotropic, layered and composite materials.
Kinematic connectors in system-level NVH The NVH modules allow coupling of the dynamics of individual components represented by modes or transfer functions or by FE or test. The coupling properties between these components are now extended to include kinematic connectors, beyond the existing flexible and rigid connectors. As such, system-level transfer functions or system-level modes can be calculated efficiently through the integrated FBS or modal coupling solver, where the subsystems are coupled by kinematic connectors.
