    Need Help ASAP

      Good day All

       

      I'm new in using simulation study on solidworks so would like to find out what i'm doing wrong

      We have a shaft and on the shaft their is a motor and winding drum on

      In the center of the shaft it has a bearing holding the shaft in place

      Im trying to get a study to see what causes the stuff to break on the armature of the motor and what i can do to make the armature stronger

       

      Attached it a picture to help u anderstand

       

      Any responds would be appreciated

       

      The motors Details

      DC Motor

      2680 kW

      91 Rpm

      315 kNm

       

      The motor picks up about 15tons

          First you should not have the center of the shaft fixed if you are trying to mimic real conditions.  I'd suggest a radial restraint (and longitudinal restraints on the edge) at the bearing contacts of the shaft.  You'll have to split the surface so only the bottom part of the shaft gets the support.  Then I'd apply what I think the applied torque is from the winding drum based on the loading condition at worst case (highest Fxd).  Finally I'd either apply what the driving torque is or maybe, as a first pass, fix that region.

           

          Remember your shaft design from college when looking at the max stress allowed.
