NVH Response Analysis

Lab NVH Response Analysis is an easy-to-use, entry-level simulation tool for predicting the noise and vibration behavior of a component, sub-system or complete model under operational loading conditions. With transparent access to all available models and load data from CAE and testing, users can integrate the best available data mix at all times. Fast modal and FRF-based prediction solvers quickly analyze a multitude of design variants. NVH specific post-processing tools help the engineering team compare actual responses with pre-defined or imported targets and optimize noise and vibration behavior. LMS Virtual.Lab NVH Response Analysis offers maximum flexibility when retrieving and applying load cases. The system accepts a multitude of load formats and types, derived from measurements, multibody or acoustic simulations, or generic loading sources. This includes structural forces, displacement excitations, and acoustic loads. The latter can be derived from structural vibrations on panels using acoustic source quantification. Combining measured loads with virtual models results in a more realistic NVH simulation as well as better and more reliable design insights. Engineers can easily set up NVH analysis runs with the template-based user interface, either starting from an FE model or using a test-based model. The solution also includes FRF and modal-based NVH response solvers to compute system noise and vibration responses. This results in fast simulation runs to process numerous design options in a limited timeframe. A wide variety of advanced post-processing tools help engineers investigate noise and vibration contributions of individual or grouped paths or modes to the final response and compare the response results with target data. LMS Virtual.Lab NVH Response Analysis supports techniques to execute design modifications from manually triggered modification analyses to fully automated design space explorations in combination with LMS Virtual.Lab Optimization.
