Achieving better Vehicle NVH performance using MSA and RBDO methods

In the context of NVH vehicle development, a common source of costly design change is where issues are discovered late in a program during vehicle testing or even post launch. Often this occurs where the simulation has met the targets including vehicle level analysis. By considering a population of results rather than the nominal CAE result, a process is demonstrated to develop a more reliable design that will deliver high levels of customer satisfaction and lower levels of late change and warranty costs. In this presentation we will introduce how this can be achieved through the use of MSA and RBDO methods within the framework of Altair’s NVH Director environment.
