Rethinking aluminum for NVH abatement: Engineers, abandon those mastics! New 'quiet' materials solutions are at hand

摘要

Engineers who have witnessed aluminum-intensive vehicles being "uncloaked" in a full competitive teardown relate the same story: After you've pulled the carpet out and stripped it down to the naked bodyshell, the "band-aids" are clearly exposed - typically on the floorpan, bulkheads, on the rear package tray of sedans, around the wheel-houses, and within the noise-critical dash panel and cowl plenum.
