PSARRP - Mobility between VCG and Ziegler

Purpose and goal

The purpose with this project is to predict the occurrence of squeak and rattle virtually with different types of analysis from CAD based analysis to advanced CAE-based analysis. The mobility project has aimed to exchange knowledge between Chalmers, Volvo Cars and Ziegler Instruments in the prediction of squeak and rattle. Volvo Cars and Chalmers has trained Ziegler in CAE-based analysis and Ziegler has trained Chalmers and Volvo in the CAD-based analysis. A total of eight people participated in the exchange. Now each part can apply respective methods individually

Results and expected effects

For Volvo Cars, the effect of exchange is that resource-intensive CAE activities can be replaced with simple CAD-based methods to identifiable potential problems. This results in more efficient use of resources and shorter time loops analysis. For Ziegler, the exchange has resulted in that they can validate their CAD analysis with complementary CAE calculations in cases where it is difficulties to understand the impact of a design concept. Chalmers will include and further develop the two proposed procedures in ongoing research projects in the area.

Approach and implementation

The exchange between the parties have taken place in several stages. First, staff from Ziegler visited Volvo Cars where training in the CAE-based method E-line has conducted at Volvo Cars simulation environment. As a second step, Volvo Cars technical specialist within squeak and rattle visited Ziegler to be trained in the CAD method Contact Point Analysis. The last step, 4 persons from Volvo Cars and one person from Chalmers visited Ziegler to be trained in the Contact Point analysis method. The cooperation between the parties will continue outside of the mobility project.
