    Bell Crank Structure

    Thank you for your kindness.. Can I ask you again that the first question I asked is not solved yet. For simulating same situation on CATIA model, I don't know exactly how to set dof of RBE2. There is travel and stress following the Force in the condition of constraints. If you know how to set this situation, can you give any advice? I sent you hm file to secure file dropbox. CAT model Condition of modeling on HYPERMESH Condition of modeling on HYPERMESH Condition of constraints on CATIA Before force on CATIA After force on CATIA Before force on HYPERMESH After force on HYPERMESH

    Thank you Ivan, I can solve the problem about surface to Rahul R, Where can I check my filedrop to you? I lost my file all of them... TT

    Bell Crank Structure

    Actually, I did not reach the OptiStruct, so I just share the file about modeling. and I have a another problem about missing surface. This image is the modeling file on CATIA and there is no empty betweent the surfaces. and this image is the imported file on Hypermesh and there is empty space between the surfacesl. I can't select the surface for meshing. How can I solve this problem? If there is a empty space, I'm worried the result is expected to be different from normal. I shared you my files, can you help me with these two situations?

    In this analysis, I'll constrain one part and apply force to the other in the vehicle. and then I want to model t he bell crank to function properly in the direction of motion.

    Bell Crank Structure

    Hello, I'm James Kim. I have a trouble with putting my bell crank into hyperworks. with line mesh wishbone, rigid (appropriate DOF setting for the situation), I make a realization of Bell Crank on hyperworks. When I click the 'Optistruct', it has occur the problem. I think problem is rigid with no element like pic(bellhyper2). I have no idea about how to make it looks like CATIA modeling. How can I construct an object that is moving in one axis direction?
  6. Sorry for lost questions. I replace all of CWELD to beam, and want to connect with beam but there is no nodes on beam and I can make a node on beam ..
  7. I want to see yield strength in my frame structure more detail not a , and I thought I had to use line mesh to connect the link in middle of the frames. j1 is beam analysis. but result value is so low, so I want to set my files more details.
  8. I sent the files. Thank you for your help.
  9. Hi, it may be lastest file thank you
  10. hmm I can't understand "remove the Beam section and provide the Diameter" How can I provide the diameter to CWELD after removing the beam section.?
  11. Hi, I have a problem with optistruct.. There were 4 error messages during input processing. The first message is repeated below: *** See next message about line 4624 from file: C:/Users/kjm96/Desktop/Frame/HW/FRFInal.fem "PWELD 7 1" *** ERROR # 1000 *** in the input data: Incorrect data in field # 4. I did assign all of property and I can't find the error thank you

    Element stress

    Great! thank you.. Can I ask one more? When I import solver deck after I save the model before analysis, there is no node on hypermesh optistruct like pic 1. Is there no way to restore the nodes ?

    Element stress

    Hmm.. I want to check if each frame member exceeds yield strength for input load. Is it correct to assume that 13N is too small to withstand the load of 1020 tubes? (Because 1020 tube's yield strength is 350 MPa) For the more correct analyze, do I have to meshing the frame member?

    Element stress

    I have applied 4000N on a node like pic1. When I view Hyperview, the frame member represents 13.57 ..

    Element stress

    Hi, I am designing frame structure. and I want to know the stress of each member. I've given member 4,000 N of strength, but output is just 13.57 ... Is it 13.57N? I don't know if it is right to analyze the results..
