The need for engine system CAE radiated noise analysis to confirm results obtained from “component - only” analysis are expensive and time consuming. This is because engine system analysis requires finite element modeling of most engine components (large modeling time) and extensive CPU time and cost to run the full FE system model. The objective of this paper is to introduce a new CAE methodology that makes use of “component - only” analysis to predict the NVH systems effect of the engine block and head, without the need of analyzing the full engine system model. This new CAE methodology evaluates the bolted joint accelerations at the engine block and head flange connections to the: front cover; cam covers; oil pan; intake; exhausts; and transmission. This new method is called BAC (Bolt Accelerations Computation). BAC, in conjunction with SVL (Surface Velocity Level) acoustic response, has been used to optimize the Ford 5.4L cylinder block and cylinder heads for NVH.
