Dear, The heat transfer or heat friction can be activated by Ithe=1in type 7 contact. As the Ithe is kept 1 you can see that the frictional heating factor, Fheat, is active in the card.

@@arsitech-ltd thank you so much for the answer.. I can't open engine file assistant on hw 13.0. Is it about software version? because I can only see radioss Block 120 forma. I think to add control cards manually because of this. Could you share that exercise file. yusufcakirca@gmail.com. Thank you.
sir i have a doubt in real life condition friction force stops the wheel as F=(nu)N but here we are not defining any normal load just giving the displacement . how the software is converting displacement into load or does it mean there is infinite load?
Dear, when brake plate and brake shoe will be in contact a pressure force will generate on both..that can be calculate by software. By that normal force can be calculated and hence frictional force.
@@arsitech-ltd sir is it like shoe will behave like fixed support and disk will behave like shear load and due to contact constrain they both will behave like a single body 😅
Thank you so much sir......but i have one doubt i simulation...i have followed all those steps bt my rotor gets expand due to velocity...i m unable to find the solution pls can u guide me!!
Dear, May your velocity is High enough to deform disc radially..if u feed random value. Also make sure material, geometry and load should have unit consistency. Sometimes its happen material we consider in MKS unit and geometry, velocity unit we assume in mm, ton, sec unit..! Rectify it.
Dear, If number of candidates are willing to learn any of following i can teach - 1. HyperMesh (pre-processing &, solver deck preparation) 2. Abaqus 3. Optistruct 4. Radioss 5 CATIA
which two output blocks are been created, and does those affect the analysis
Dear,
Output block doesn't affect the simulation. It is just for specific output request.
Thank u for this good tutorial Sir. But when I do same thing on video. My disc is deforming by brake pad very much. How can I fix?
Dear,
Please Check you Material parameters or scale factor in post processing.
hi sir why velocity rotation just 0.4 rad/s ? it so small
Dear,
watch video carefully. In the beginning of video itself I mentioned unit is in mm,tons, milliseconds.
@@arsitech-ltd thanks sir i got it
Is it perform in ansys
Hypermesh with Radioss solver. But such simulations can be perform in Ansys. Not only Ansys but also in Abaqus, LSdyna and many more.
Very much informative
Hi. Thanks for informing video.. How can we obtain the frictional heat generation?
Dear,
The heat transfer or heat friction can be activated by Ithe=1in type 7 contact. As the Ithe is kept 1 you can see that the frictional heating factor, Fheat, is active in the card.

@@arsitech-ltd Thank You so much Sir for ur solution👍👍
Hidden gems on internet.
Dear,
Share with others, make it visible to all.
@@arsitech-ltd sure sir.
Hello Sir,
How to give rotational velocity in Optistruct
U r great sir... Nice vdos
Thanks for appreciation.
Hi sir at V_r you use V_r= 0.4 rad/ms of V_r = 0.4 rev/ms
thanks sir
Can u upload this file on somewhere ? I need it to analysis. And thanks for this channel
Dear,
May i deleted this file when i cleaned my hard drive..if it is available I'll let you know.
Dear Sir, I want to take this couching online
Dear,
If number of candidates are willing to learn any of following i can teach -
1. HyperMesh (pre-processing &, solver deck preparation)
2. Abaqus
3. Optistruct
4. Radioss
5 CATIA
Hello Sir, Can I get deck model for the same
Dear,
I can provide only CAD model of it
@@arsitech-ltd okay..Please provide
Hypermesh- practice model- brake plate
drive.google.com/folderview?id=1Sbcv6kPcvTAvEM1EK2JhRMIHskCbcebW
Wonderful tutorial. .can I get cadd file of this too sir..
Plz provide mail ID.
@@arsitech-ltd Did u receive my mail I'd sir anto.naveendp@gmail.com
sir i am getting error 760
me too🤧🤧, can u fix it???
Dear, I not remember this error. I stop working on Radios solver.
Sir please upload video on brake squeal simulation too.. please
Dear,
By checking the combined frequency of the brake system we can interpret squeal.
Nice simulation could you share me your input file?
Dear,
You can find CAD file from link - Hypermesh folder drive.google.com/folderview?id=1Sbcv6kPcvTAvEM1EK2JhRMIHskCbcebW
And follow the procedure.
