Case Study: Volvo Group achieves faster vehicle NVH optimization with Cadence MSC Nastran FEA Solver

Volvo Group cuts NVH analysis time by >99% with Cadence

Volvo Group, a major manufacturer of heavy-duty trucks, sought to reduce cabin noise and vibration (NVH) to improve driver comfort. Their NVH team faced the challenge of predicting vehicle-level performance efficiently, as traditional methods were extremely time-consuming given the numerous vehicle variants and constant design changes during development. To address this, they utilized the FRF-Based Assembly (FBA) module within the MSC Nastran FEA Solver from vendor Cadence Design Systems.

The solution from Cadence allowed the Volvo team to analyze individual truck subsystems and then combine the results to predict overall NVH performance, eliminating the need to repeatedly analyze a full vehicle model. This FBA approach yielded results that correlated well with conventional methods while saving significant time. In one application, the process led to time savings of over 99% for evaluating design changes. The implementation by Cadence drastically accelerated design cycles, enabled quicker feedback, and helped Volvo achieve an optimal, feature-balanced vehicle design in a much shorter timeframe.
