Summary:

Today's power train applications have increased dynamics,loads and temperatures while requirements for NVH increase andpower train packaging offers less space for shielding components toprotect surrounding parts.Short development timing requires the use of FE analysisforecasting durability, natural frequencies, stress levels andstructural parameter. While these parameters nowadays can be dealtsuccessfully with available simulation tools, it is still complexto understand acoustical effects occurring at dynamically excitedheat shield applications which moreover depend on each other. Thedesign (form and material) and assembly of the majority of themulti-layered heat shield components affect their acousticalbehavior. Due to the fact that application temperatures rangebetween 150°C at underbody parts and nearly 1000°C at hot ends,suitable materials have to be chosen.This publication describes which acoustical effects can occur onheat shields. Furthermore this article describes what kinds ofmaterials are available for the wide operation temperature spectrumand how to reach adequate solutions realizable in applications
