Development of a Lightweight Soundproof Cover Using the Biot Theory (Vibration Propagation in Elastic Porous Materials), and an Example Application to a Transmission 2016-01-0517

To reduce cabin noise and vehicle weight (for lower fuel consumption), a lightweight soundproofing cover was developed as a countermeasure to sources of noise, using the Biot theory (vibration propagation theory in poroelastic materials). This report also presents the results of its application to a metal belt-type continuously variable transmission (CVT) used in Toyota Motor Corporation’s 2.0L vehicles.
