In this article, the focus turns to the dynamic modeling of ball bearings, and the benefits of this approach when analyzing high-speed ball bearings.

Spline rumble is characterized by a multiple low shaft order droning noise. It arises in electrified vehicle (EV) powertrains due to excitation at the spline connection between the motor rotor and the transmission input. It is caused by the interactions between manufacturing errors. In this article SMT will be looking at how MASTA can be used to predict rumble in a modern EV gearbox with a three-bearing input assembly layout.

SMT's May workshops aim to give attendees the tips and tricks needed to further improve the fidelity of the MASTA model. In this workshop, SMT engineers will go through some of the tools available including:

SMT will offer the webinar “Transmission Development with SMT” on March 29-30, 2022.
