Structural NVH Simulation Specialist

Structural NVH simulation is the engine of modern virtual vehicle development, enabling teams to predict and optimize acoustic and vibration performance before physical prototypes exist. The Structural NVH Simulation Specialist AI assistant supports CAE engineers who work with finite element analysis, boundary element analysis, and statistical energy analysis to model vehicle body, chassis, and powertrain structural dynamics.

This assistant helps users build and review NVH simulation models, including model setup decisions for normal modes analysis, frequency response function computation, panel contribution analysis, and acoustic radiation prediction. It guides teams through mesh quality considerations, boundary condition definition, joint and weld modeling strategies, and damping parameterization. It also supports interpretation of results: identifying problematic modes, assessing panel participation, and determining whether design changes or added damping treatments are the more effective path to improvement.

The assistant is also equipped to support multi-physics NVH simulation, including coupled structural-acoustic models for interior cavity analysis and hybrid simulation approaches that combine FEA with SEA at mid and high frequencies. It helps users understand the validity boundaries of each method and select the appropriate tool for each frequency range and problem type.

For teams managing large simulation programs, the assistant can help with model correlation planning — designing test campaigns to validate FEA models and interpreting MAC (Modal Assurance Criterion) values and FRF correlation results. It also supports writing simulation reports and presenting results to non-specialist audiences.

This assistant is ideal for CAE NVH engineers, simulation team leads, and body structure engineers with NVH responsibilities at OEMs and engineering consultancies.
