Advances in the Development of Vehicle Refinement Using Virtual Test Rig Applications Based on Real World Test Data
As manufacturers demand greater levels of refinement from their vehicles while at the same time looking for reductions in development costs, IDIADA has identified new ways of integrating the real world test environment with rapid simulation technologies to reduce development time and increase performance.
Combined with feedback from customer surveys IDIADA has identified which surfaces with its facilities and surrounding public roads are most valuable in the development of ride comfort and NVH. The profiles of these surfaces have then been meticulously measured at high resolution and further characterised according their specific content.
These surfaces have now been prepared for use in the simulation environment where chassis developments can be advanced more cost effectively. Using efficient simulation procedures together with improved model definition for example, NVH engineers can analyse the interaction of engine and suspension to ensure harmony is maintained between them.
This paper describes the process that IDIADA has adopted to measure the road surface profiles and the analyses conducted. Examples of full vehicle simulation results using a correlated vehicle model using these profiles are presented. Finally, the incorporation of these new techniques in the chassis development process is presented and the benefits discussed.
