TENCHIU GRASP, MY MAN
Thanks..What?
fixed support means it will fix everything .
displacement support means it will fix Rotational degrees . where as displacements can either be set to free or fixed. is my understanding correct sir.
Displacement constraints are used for translation dof in x, y, z direction. For rotation & translation together, remote displacement will be used. Sometime we have displacement (ex. Thermal displacement) values in x, y, z, so we can apply displacement BC.
Thank you very much for the video, can you make one video by exploring the joints. I am very much interested and looking for bearing type of joint between 1D Shaft and surface where the bearing is mounted. Thanks in advance.
Thanks ! We will make video !
@@graspengineering9249 can you please send any quick reference document for body to body bearing joint, I am need to solve that by tomorrow EOD. Please send to my mail ID if any document is available ( muralikrishna.puppalla@gmail.com)
Dear Sir...u hve xplained all d topic very nicely..i am a working professional...n i would like to knw..hw to do fatigue analysis for multiaxial loading in ansys..i hve alrdy written on it...it wil be glade if u can help...!Thank you..
Hello, Greetings!
For any fatigue analysis you need to first find out peak and valley conditions. Like in your case you might consider peak condition as multiaxial maximum load value and valley will be minimum load value. Then do FEA, use mean stress correction and then find our fatigue life. If your product belongs to pressure vessel or offshore structure, ASME and DNV standards have separate menthodalogy, you can prefer for your simulation.
@@graspengineering9249 i am belong to automobole background..n i want to do fatigue analysis for a biaxial loading,both loads wil b cyclic in nature..one is reversal(R=-1) in both direction and another one is repeated(R=0) in one direction...so nw challenge is in combine both d load n apply proportional cyclic loading on dat...i am looking forward for ur help...my whtsapp no..9435798463..thank you.
thank you sir
Welcome !
Sir can you help me? I try to apply the roller support but it doesn't want to. I checked the surface but to no avail. can you help me
Thank you very much!
Welcome !
Hi..in case of frictionless support you r telling that it is constrained in x direcrtion in translation and rotation. Translation part is ok but rotation w.r.t x axis means basically it is rotating in yz plane which is possible in case of frictional support as in case of frictionless support it allows movement in yz plane then how is it constraining rotation w.r.t. x direction. Isn't it? Can you clarify that plz?
Frictionless support provide constrained in normal direction. Please Check this blogpost for more clarification. www.graspengineering.com/what-is-frictionless-support/
well explain
Thank you
Hi,
I have 4 wheels mobile cart and some load on it and it's CG is not at the centre, how can I simulate in ansys my mobile cart is going to fall due to load or not.
Please help me on this
Regards
Hello,
1. You need to model the mobile cart and
2. Idealized weight with mass elements and
3. Apply at the center of gravity.
4. You can fix bottom rollers of mobile cart in all dof.
Check reactions with operating weight and report the stresses and deformation.
Frictionless Support: 4:12
Yes !
Please please please , can you explain more the last technique (3 2 1 supports) ? if we want to fix it why can t we use the fixed support in place of fix the points like that ? really that will save me thank you very very much
Greetings!
Fixed supports means all dof fixed and used when your equipment is either hold completely or locked in position.
In case of fork lifting, only vertical movement is restricted and hence better to constraint in vertical direction only, But if your mounting weight is not symmetric the solution will not solve will show rigid body motion error. In this case we can use 3-2-1 just to avoid rigid body motion by constraining few nodes. It is FEA assumptions only. You can use fixed support to but it might shows high stress.
May God bless you
Thank you!
Can you make video on saddle design with calculation
Okay ! You can refer ASME or TEMA standard for saddle design. Just follow the guidelines and perform the calculations.
Dear Sir,
Could you please create video series on non linear analysis as per ASME sec VIII, Div 2, part 5.
We have few videos on fatigue analysis, stress linearization on our channel page. It is not possible to cover all the topics on RUclips. We are planning to create complete coarse on ASME sec VIII, Div 2, part 5, you can subscribe once we share the subscription link.
@@graspengineering9249 Dear Sir; Did you create complete coarse on Asme sec VIII div 2 part 5. I did not see any coarse on your chanel or your webpage.
and I thank you for your videos.
@@mertsenol6000 Still working on it. It is taking much time than estimated, will let you know once done.
@@graspengineering9249 I am looking forward to it.
can u make one video on type of contacts plz!
Okay. It is difficult to cover all the topics in video & hence we are working on ANSYS detail coarse which will give complete knowledge of ANSYS which includes linear & nonlinear contact too.
Plz sir I need that very badly
Okay ! You can refer ASME or TEMA standard for saddle design. Just follow the guidelines and perform the calculations.
