I'm trying to simulate a driveshaft from a conveyer system with COSMOSMotion 2008.
The shaft is driven on one end and restrained in two self aligning bearings on both sides.
I've tried different ways of simulating this situation, but I just can't get it right.
Using the standard restraints I can’t get the shaft bending in the way this would happen in real life. (the way COSMOS 2010 has the possibility to choose from self aligning bearings as restraint)
Using “tool-components” for making the natural deformation of the shaft possible results in deformation of those parts as well. This does show believable outcome for the values of stress but does not show a coloured plot of only the axle because of immensely high stresses in the “tool-components”.
Which is the best way of restraining the shaft to get a right outcome for the stress and have a plot which shows the stress distribution in only the axle?
