Awesome videos on ansys, easy to learn with these examples 🙏
Great work!!
Could u please share the link for the robotic arm so that I can follow along
Thanks for the video...changing the property "rigid" from "flexible" effect the results?
Why do you suppress the contacts? Causes it not to mesh
What do you think about the deformation is too high?
When you doing dynamic analysis or transient the deformation you see that deformation of object but the transient deformation is not a deformation of body, it's the displacement or the position of the body travelling from one place another place.
Don't confuse by static deformation and transient deformation, the name is same not the results
@@Bharathacad Thanks a lot for responding to my question.
Could you please explain to me about the deformation is 1039.8 mm? It is too high?
Do you think we should include standard earth gravity in the analysis?
Not for this example
@@Bharathacad why?
@@Bharathacad Also in my analysis of joint probe value here, it turned out to be a very low value. Its maximum value is 0.5N. What do you think is the reason for this?
the bodies are rigid
i didnt used any kinds of friction or contacts in it, so there is no oppose forces
How to find stress?
Can u plz share any examples on spherical joint.
I will try with suitable example
@@Bharathacad thank you
I am trying to find the stress-strain distribution using transient structural over robot arm but I got problem in convergence. Are you provide solutions?
hi do you know now
the arm how did you do it sir
Why did you use 60*8 in Number of step?,where did came from 60 ?
8 links * 60 steps
@@Bharathacad can you let me know more about time steps?
Do you have any videos or materials explaining them?
hello sir , can you provide the design model
Sir, I tried to apply this analysis to my own robotic arm design like you. But there is a problem in the simulation. After 1 to 60, the piece does not continue to move from where it left off, while it is from 60 to 120. I mean it moves from 1 to 60, but at 60 it comes back to the same position and does the other move. Even though I did the same things you did.
I tried to fix it bu couldn't mananed it. Can you help me?
If it's easier, I can send you the analysis so you can see more easily what the problem is.
Did given all possible connects correctly
@@Bharathacad ı suppressed contacts like you did. And All joints are Revolute except the base part it is fixed to ground.
@@Bharathacad if you send me an e-mail ı can send my catia design and ansys analysis so you can check it easly?
@@Bharathacad Will you help, sir?
Hiiii bro .... I'm not getting the explode option in my Ansys workbench 15
rohit bhat that options is available in 16 and above
How can explode in Ansys 15 version
Hi, what is the difference between RBD and Transient Structural ?
Rbd we can see any mechanism with help of the connections joints. Transient is we see stress and strain changes over the body during mechanism
thx
can you please provide 3d model of the robotic arm or link
+Vids viral go to grabcad you can find the model

i wanted the model parts you can send me google drive
