While companies can solve automotive engine noise problems by using engine mounts to stop vibration and the firewall to stop airborne noise, these solutions are not sustainable if one wishes to maintain quality. Therefore, car manufacturers taking advantage of finite element analysis (FEA) software to better understand noise and vibration. FEA can be used to track the propagation of noise, detect the source of it, and perform vibro-acoustic analysis. Compared to physical testing, FEA can save manufacturers a significant amount of time and money.

MSC Software develops leading technologies to address all aspects of problems in the field of NVH with Multidiscipline (MD) simulation tools. MD Nastran and MD Adams provide a unique multidisciplinary solution for NVH simulation, with capabilities that span linear and nonlinear statics, linear and nonlinear dynamics, modal and frequency analysis, thermal and coupled structural acoustic analysis, multi-disciplinary optimization, and comprehensive system motion simulation. Together, MD Nastran and MD Adams provide a complete integrated solution to address the many challenges of NVH simulation.

As a result, with MD solutions, engineers can simulate the NVH performance of a full vehicle system. With the power of MD Nastran and MD Adams, automotive manufacturers can reduce the need for costly physical testing while improving automotive NVH. These MD solutions provide the capability to study the effects of multiple disciplines under the same software environment with increased accuracy of simulation results, all while reducing the time and effort in the traditional NVH design process.
