N2 - Reducing noise propagation in mechanical structures can be difficult when several components on multiple intersecting transfer paths interact. One way to reduce design complexity caused by the transfer path interaction is to derive component requirements from the system design goal. The component requirements should ensure that the system design goal is reached whenever these requirements are met. In this paper, we present an approach that computes solution-neutral requirements on isolation elements of multiple connected transfer paths, such that each of them can be developed independently and efficiently. This is accomplished by first modeling the system dynamics with Dynamic Substructuring and Transfer Path Analysis. Secondly, the ranges of admissible stiffness of isolation elements are quantitatively expressed as a so-called solution space for each isolation element. The proposed approach is applied to the noise propagation path of an electric compressor in a passenger vehicle.
