    How should I constrain a moving cylinder in abaqus?

    Thank you for the feedback and hints. I have also thought about the dynamic aspect, but in my analysis I want to look at the exact moment when the piston rod presses on the plate via the lever. In this case it should be static or not? In other words, the rod should not move first. However...

    How should I constrain a moving cylinder in abaqus?

    Hello together, I have a question about the interactions and constraints in Abaqus. I am doing a static analysis and I am modeling a cylinder that is rotatable on two sides (see picture). The cylinder rod is movable in y-direction and pushes with a force on a plate via a lever. I am now...

    Define bolt load with normal screws in Abaqus

    Hello FEA way, thank you for your quick respond. Yes, the threads were not modeled because I wanted to do a simplified calculation. Here is the screenshot. Unfortunately, I didn't find anything about it in the forum, where only the connection between a screw and a nut is discussed.

    Define bolt load with normal screws in Abaqus

    Hello together, in my simulation I use bolts with nuts (simplified) and normal bolts with threads that are screwed in a hole. I don't get any error messages with the screws with nuts, but I don't know exactly how to interact the normal screws with thread. Do I have to create a tie constraint...

    What restriction or condition for a spindle running in a linear guide (Abaqus)?

    I would like to do a static analysis where the bottom of the spindle presses on a surface. I just have no idea how to connect/constrain the spindle and linear guides... If I connect the spindle and linear guides with a tie constraint, the spindle will be held although in reality it could...

    What restriction or condition for a spindle running in a linear guide (Abaqus)?

    Hi FEA Way, thanks for the quick feedback! Exactly, the yellow spindle should be able to slide in the blue guides. I connected the blue guides to the red bracket via tie-constraint and held the bracket in place at the back. I tried it now in the assembly via position constraints, is that the...

    What restriction or condition for a spindle running in a linear guide (Abaqus)?

    Good evening everyone, I am currently modeling in Abaqus a spindle that is suspended and can move downwards in a linear guide. The spindle pushes at the end with a force on a body. I just have a problem how to couple the linear guides and the spindle without restricting the movement. Everything...

    Error in defining a Bolt load in Abaqus

    Hello FEA way, thank you for your response! I tried "Bolt Shank Surface" but still get the same errors... -in keyword *CLOAD, file "Job-3.inp", line 260899: Unknown part instance set ZYLINDERSCHRAUBEM6-1._BL-M6_BLRN_ -in keyword *BOUNDARY, file "Job-3.inp", line 260937: Unknown part instance...

    Error in defining a Bolt load in Abaqus

    Hello all, I am doing a stiffness analysis of a bolted beam and I have a problem with the bolt preload. I created a surface in the middle of the bolt shaft and then created the preload using bolt load. However, it is not transferring the preload to the other bolts in the assembly even though I...
