Description:

In the attached models an angular misalingment in YZ (around X axis) is applied at different axial positions. 

Also the clearance of the bearings and the shaft stiffness (hollow instead of solid shaft) are varied.

The models will demonstrate and explain the effect of the axial position of the misalignment (and clearance or shaft stiffness) on the reaction forces on the bearings. 

A detailed explanation can be found in the report of the corresponding model.

• Option 1: misalignment YZ (around X) in centre of the shaft (z = 110 mm)
• Option 2: misalignment YZ (around X) moved (z = 60 mm)
• Option 3: misalignment YZ (around X) at (left) bearing position (z = 10 mm)
• The clearance is varied in two steps
