Problems solved by technology

[0006] However, in the actual motion of the rolling-sliding pair, it is not stable, but accompanied by external excitations in different directions and different loads

It is very important to study the influence of external excitation on the motion of friction pairs. None of the above disclosed inventions proposes a better way to carry out rolling experiments under external excitation conditions.
