Virtual Rig Simulation in the Exhaust System Development

A newly developed approach, Virtual Rig Simulation for exhaust, is introduced in this paper. An OEM exhaust system durability performance is simulated and simulation results are correlated to test results. The correlation results prove that the Virtual Rig Simulation predicates critical locations very well. The modal transient analysis is applied and input loading is from full event RLDA data. The advantage of the approach is that it can be applied in upfront design stage to predict exhaust system durability performance so that test cost and time are reduced significantly. Also, the presented approach is not only useful for exhaust system development but also useful for other product development.
