Frequently Asked Questions
How can I predict noise and vibration in the concept development phases when there is insufficient detail in the design?
Even without predicting the exact NVH behavior, you can use Spectrum early to benchmark competing concepts and iron out major issues before it's too late. As the design evolves, you can quickly re-assess performance with greater confidence.
We already have a tool for FE - why should we pay for and have to learn another tool?
Spectrum offers much faster CAE processes and is dedicated to transmission and ePowertrain with proven accuracy and simulation efficiency that works with and compliments your FE simulations.
Don't I need time-domain analysis to gain accurate NVH results?
The Romax frequency domain analysis is fast, highly accurate and generates easy-to-interpret results. As such, it can be used very early in the design phase, meaning potential issues can be identified while they’re easy and cost-effective to fix.
The parametric nature of Romax Spectrum, combined with short runtimes, means design optimization is also possible. As the design matures, fully detailed Spectrum models can be used alongside Adams to ensure all potential NVH issues have been investigated.
