Plastic air induction system being mounted in the engine compartment is subjected to high magnitude of vibration acceleration loads. It is essential to determine the structural integrity of the AIS component under this. Therefore durability analysis of an AIS assembly of an SUV is performed here. In this project work the frequency response and dynamic stresses in the AIS structure were simulated using the steady state dynamics.

Plastic air induction system being mounted in the engine compartment is subjected to high magnitude of vibration acceleration loads. It is essential to determine the structural integrity of the AIS component under this. Therefore durability analysis of an AIS assembly of an SUV is performed here. In this project work the frequency response and dynamic stresses in the AIS structure were simulated using the steady state dynamics. The acceleration response and dynamic stresses in the AIS structure due to vibration acceleration loads were determined, subsequently the high stress region in the structure was identified and the life of the structure at this region was determined. It was observed that, the preliminary AIS design was safe for all loading cases except vibration acceleration loading of 8g, wherein the high stress region in the AIS structure under this load has a minimum life of 1E7 repeats. Therefore this region is prone to failure, however by increasing the wall thickness in this region by 35 %, the minimum life increased by 30 %.
