Hi all,
I'm currently working with ANSY WB version 12.0.
I have a steel pipe flange connected to an aluminium casting via three bolts. To simplify the model I have modelled the bolts as beam elements in ANSYS Mechanical using the "connection - beam" functionality and joined my casting hole to the nut hole. This works fine and I have managed to run my model.
I have added a beam probe which tells me the following:
Axial Force = 1074N
Torque = 20Nmm
Shear Force @ i = 408N
Shear Force @ j = 408N
Moment @ i = 1230Nmm
Moment @ j = 2569Nmm
The things I am struggling with at the moment are:
1) Identifying the sign conventions for the beam probe output and consequently drawing the FBD.
2) Calculating (by hand) a stress from these figures to allow me to compare it against fatigue material allowable stress ranges.
Any advice/guidance would be very much appreciated!
