Smart testing combined with selective virtual modeling -
The key to resolving noise and vibration problems is smart testing combined with selective virtual modeling. A selection of measurements is recorded at critical locations on and around the product. Transfer path analysis then traces excessive noise and vibrations back to their source. This capability provides deep insight into the ways a structure generates noise and vibrations.
To predict the effects of design modifications, LMS Engineering Services builds virtual models of the entire product and validates their accuracy against test data. Numerous variations of these models can be exercised to evaluate product behavior.
In some cases, LMS integrates test data from existing components with simulation data of new parts and assemblies. This hybrid approach uses the most reliable model and load data throughout the design process, combining the reliability from test data with the flexibility and cost-efficiency of virtual modeling. Feedback from physical prototype tests allows us to update virtual models and calibrate early assumptions, which provides a strong foundation for future modeling.
