Objective
The principle and overall scope of the project is to develop, implement, evaluate and validate an integrated approach to the problem of structure borne noise transfer in cars.
The objective was to develop, implement, evaluate and validate an integrated approach for structure borne noise analysis in cars. This approach was based upon existing techniques and newly to develop techniques.
The goals to be achieved were threefold:
- Evaluation and limitation setting of existing techniques.
- Development of new techniques.
- Integration of different techniques into one global methodology.
The first objective of the project included the investigation of the advantages, sensitivity to boundary conditions and limits of confidence of general classical techniques in the field of structure borne noise analysis at several testvehicles. These techniques were amongst others : single input, transferpath analysis, principal component analysis, mount testing.
The newly developed techniques were related to algorithms for indirect force determination, high quality FRF measurements, time domain principal component analysis and advanced mount testrig.
Finally, the different techniques have been integrated into two global methodologies : Engine Noise Analysis and Road Noise Analysis. This integration resulted in a new software code.
As a general conclusion all partners agree that the project has been carried out as originally planned and that the objectives are reached.
This aim achieved through two major subtasks : firstly, to build experiences so as to define the practical behaviour of validity of each of the techniques involved, secondly, to integrate the methods in a single approach to the problem of structure borne noise in cars.
The projet aims at evaluating the limitations and assets of techniques such as transfer path analysis, partial coherences and noise analysis by principle components. The evaluation will be based on theoretical and scientific elements in order to identify the complementary parts as well as the eventual overlaps. Strong emphasis will, however, be put to the applicability in an industrial environment by investigating the consequences of the theoretical developments upon the practical use; the effect of prtical simplifications upon the accuracy of the results will be considered to be very important.
Through the evaluation of those techniques, the project aims at integration of the analysis results, and the formulation of an interpretation scheme.
From result integration, the project focuses on the integration of the methods themselves, so that not several measurement sessions but only one integrated session has to be carried out. The definition and implementation of the integrated approach will adhere to an open system architecture as well as to current standards for user interaction and develop pre-competitive data processing and handling techniques so as to allow automation of the approach. 2
