Hello,
I'm working with an automotive wheel hub design. The design has two taper roller bearings in a "back-to-back" configuration. The taper roller bearings connect the hub(and attached wheel) to the spindle. This is a straight axle truck application in a 4x4. I've done lots of analysis of this type and I've been hoping somebody might have some similar experience. In the case of the taper roller bearings they have a "contact angle" between the cup and cone. This means that radial forces also generate axial forces and such. So, my models generally model the cup and cone as a solid steel hunk with the correct contact angle between them. Then I assemble the hub, spindle, and bearings into an assembly. Once this is done I go through and input all the boundary conditions. My problem isn't that I'm not happy with this type of analysis but that it isn't totally accurate(as with everything). The stiffness of the taper roller bearings is over estimated by the way I've modeled them and done the analysis. Is there anyway better way to model and do analysis on taper roller bearings? Do you have any experience with taper roller bearings to share?
