Tracking movement of shafts in a housing deflection study

Tracking movement of shafts in a housing deflection study

Tracking movement of shafts in a housing deflection study

(OP)
I'm analyzing a gearbox housing for deflection effects on the gearing.

This means that I want to know the relative motion of one shaft axis to another. The shaft axes don't exist in the housing model, only the bores that hold the bearings. I would like to represent each shaft axis and query the relative movement of one shaft axis to another.

Right now the best thing I can manage is a datum point at the bearing center connected to the housing bearing bore. Then the x,y,z movement of these datum points must be evaluated manually. Anyone have a better way?

RE: Tracking movement of shafts in a housing deflection study

You could connect a datum point using rigid links (or springs, or weighted links, depending on whether you want to model the stiffness of the bearing itself). Create measures as you suggest for the location of the datum. Then create a computed measure - this is an incredibly useful tool where you create a measure based on other measure's values and some mathematical expression.
