    Force on bolt under tension

    Oshri Nitzan


      I am
      having a problem with the result I am getting on the solid works simulation

      I made some study to calculate the force acting on bolt in addition to see if this
      bolt will be in the yield zone in my study case

      So I took 2 plates will 11 mm hole and put a bolt connector M10 with nut


      I preload the bolt with 19.7 N*m and the axial force I got with the pin/bolt check was
      just like calculation I made on paper: 9850N. This was the good part2.JPG


        Next thing I did was to put external force on the bolt witout any preload/
      the force on the bolt was 1524N


        WhenI add an external load that to the bolt I thought that I should see that the
      total force on the bolt will be:The preload force + the external force= 9850+1524=11374N

      But the program show me something else: 10148N



      that somebody can explain me why?
