| SEA Implementation into Acoustic Program Integration Process |
SEA analysis plays
an important role in soundpackage development throughout the entire process
It is a sensitive tool for
geometry and material changes and it is easy to process
There are 3 main phases in
soundpackage development: |
| |
Pre-Development Phase (40-20 months before
production) |
| | |
Acoustic, geometric and component are the 3 properties defined in this phase.
Benchmark targets are being determined and all of this information is implemented
into the program |
| |
Prototype Phase (20-0 months before production)
|
| | |
-Design material modifications are performed based on a variety of reasons
-SEA is recommended to support the program during the time CAD design changes are
implemented into the vehicle model
-SEA plays a significant role in defining the final acoustic design and the
optimum material release for production |

Production Support |
| | |
As target verifications are being evaluated primarily by testing, SEA becomes less
involved | |
| Auto SEA Component Modeling |
| HP Pelzer has developed detailed models for all major components; Dash Panel, Floor
Panel, Side Aperture, Roof and Trunk. These comprehensive models plan an important
role during the development process. Component-detailed models on past and current
programs have resulted in design recommendations, as well as material suggestions.

| Auto SEA Full Vehicle Modeling |
| The whole vehicle model allows us to analyze mid-to-high frequency ranges without
available hardware. This in-depth vehicle model consists of more than 500 sub-systems,
including all important acoustic car panels. The interior compartment is
characterized by 52 airspaces (inner cavities) while the exterior consists of 26
cavities. |

Experimental Test - Full Vehicle Measurement |
|   |   |
For benchmarking, target setting and finally
soundpackage optimization, many types of full vehicle measurements been performed during
development. |
