System-Level NVH

Lab System-Level NVH is a comprehensive solution offering a wide range of tools to assemble components into hybrid system-level models and analyze noise and vibration performance under operating conditions. Engineers can easily build a model from one or more components, including FE components, test-based components or even CAD components. Components are connected by point connections with specific connection properties ranging from rigid connections to any particular frequency dependent complex stiffness. As the development proceeds and more detailed component models become available, different model parts can be gradually refined with more detailed FE or test-based component information. Once the simulation model is built, LMS Virtual.Lab System-Level NVH calculates the assembly’ s global dynamics using internal FRF-based or modal-based assembly solvers. The resulting assembled model consists of a set of transfer functions or modes that guarantee maximum accuracy and optimal speed for full-system noise and vibration assessment. To predict noise and vibration behavior under operating conditions, the assembled models are combined with input loads from measurements, multibody simulations, acoustic simulation or generic sources. The solution computes noise and vibration responses using the internal modal or FRFbased forced response solvers or, optionally, an external FE solver.
