    Fatigue Analysis on Shaft

    Elliott Tuthill

      I have a rotating shaft that experience three loads. One load is due to a pulley on one end that rotates the shaft but also pulls it. The other two forces occur from the two bearings that support the shaft. I have a picture below of the three forces acting on the shaft.


      The three fixtures I used are two fixed hinges at the two bearings locations and a roller/slider right above the lower bearing on the surface that forms a 90 degree face with the bearing location.


      What I would like to do is a fatigue analysis that uses these three loads and simulates what the fatigue will be as they are rotating around the shaft. Does anybody know how to set this up in Solidworks?

      Below I attached the solidworks file

          You need to make the system is "fixed" to the environment.

          The fixtures that could be used: one bearing (lower) as FIXED support, while the other bearing (upper) as ROLLER/SLIDER support.


          The pulley load could be modeled as a TORQUE.


          Run a STATIC simulation first, using the input.

          Use static simulation as an EVENT for FATIGUE simulation.


          Because it is alternating load, use R= -1

          Define number of cycles?


          Define material (or use default structural steel).

          RUN fatigue simulation.
