Abstract
The transmission mount in a powertrain mounting system is often a primary path for noise. This is especially the case when the transmission is mounted directly to the body without the benefit of a structural frame or isolation between the bracket and body. Since most transmissions generate frequencies above 150Hz, the transmission mount system becomes a likely noise path for this and higher frequencies.
A combination of very stiff transmission bracket and very soft rubber mount between the transmission bracket and the transmission would help this problem. In this paper the development an optimally designed transmission mount for a longitudinally mounted powertrain is presented. The development procedure of such a design considers the transmission mount as part of the total system.
