neoTPA
Development and implementation of a method for targeted model-based NVH optimization using numerical transfer path analysis (NTPA)
Motivation
In the context of model-based product development, virtual prototypes help in the earlier phases of the PDP with the prognosis of product properties as well as for checking the fulfillment of requirements and functions. However, due to the size and complexity of the model, root cause analysis and optimization are often a challenge. Thus, the potential of model-based approaches for NVH investigations is not fully exploited nowadays. Especially in the transfer paths that depend on the structural dynamics of the overall system, there is usually great potential for optimization, which nowadays often cannot be fully exploited due to the lack of methods and tools. There is therefore a need for structured and targeted analysis and optimization options for numerical models for NVH investigations that are linked to the experimental transfer path analysis.
Research objectives
As part of this project, a software product is to be developed and implemented, and the service portfolio is to be expanded. The software product should include an innovative method for targeted model-based NVH analysis and optimization. The method is intended to combine the advantages of model-based product development with the in situ TPA method known from measurement technology.
