Predicting unloaded gear rattle using DRIVA - collage of graphs and diagrams.

Predicting Unloaded Gear Rattle Using DRIVA

, ,
Senior Research Engineer, Simon Terry, looks at unloaded gear rattle: why it occurs, how it relates to engine torsional vibrations and how MASTA’s DRIVA modules can be used to accurately model rattle in a vehicle on-road scenario.

High-Speed Ball Bearings – Dynamic Models

, ,
We look at the dynamic modelling of ball bearings, and the benefits of this approach when analysing high-speed ball bearings.
Predicting spline rumble analysis in MASTA CAE Software.

Predicting Spline Rumble

, ,
We look at how to predict rumble in a modern EV gearbox using MASTA, covering quasi-static analysis, a time stepping analysis and manufacturing errors to see how different errors contribute to rumble.
