Understanding what the Activity Index is
Powertrain transmission
A typical Activity index analysis of a powertrain transmission model is presented hereafter.

From the design point of view, engineers will only be interested in the elements with a high contribution among the total activity. Other elements with lower activities can be ignored when considering similar input scenarios applied to this model.
