Source: Škoda Auto, a.s., internal materials Comparison of the contact patterns obtained in the experiment with the MBS simulation shows very good agreement (Figure 9). This makes it possible to assess the effect of radial clearance on the load carrying zone using only a simulation calculation method with sufficient accuracy and certainty of the correctness of the results.

Figure 9: Comparison of real contact pattern with MBS simulation

Source: Škoda Auto, a.s., internal materials The effect of the radial clearance of the bearings was then simulated in the calculation in three steps, always at a load of 30 Nm. First step: arrangement with real radial clearances of both cylindrical roller bearings 0.16mm (Figure 10a). Second step:
