Hi everyone,
I have a question about bushing joint in ANSYS. I'm using ANSYS 14 but will have access to ANSYS 15 soon.
I'd like to effectively create a spherical joint which has some stiffness and damping in the rotational degrees of freedom (DOF's). I think I can do this by using a bushing joint. I'd first like to effectively lock the translational DOF's by entering high stiffness values into the worksheet. I then plan to proceed by gradually tweaking the stiffness and damping values for the rotational DOF's.
My problem is that I'm having trouble finding out which boxes in the worksheet to enter the values into. It looks like there is a 6x6 symmetric matrix of stiffness values and a corresponding matrix of demping values that I need to fill in.
Can anyone explain to me how to accomplish this please?? Also if anyone knows a better way to do this it could be helpful. I've read in the ANSYS help that it is more efficient to use "Joint DOF Zero Value Conventions" instead of entering very high stiffness values to lock the DOF's that I need to, but I can't figure out how I do that.
Any help would be much appreciated. Thanks.
