Tips and trick gear mate vs contact

[myterribletube]

HOW DO YOU MAKE GEARS SPINNING AROUND IT'S AXES,,.. my gears spin so strange,..

[botanibea]

@myterribletube try to put them concentric to something else.

[myterribletube]

My gears don't spin around axis but are just still. How do I do this. Pleas help

[wrangleroooo]

thank you, you really helped me out

[oraldinho]

nice video !! i will make a very similar analyze to this but it will be vibration analyze. I used to think using abaqus or ansys but i saw you used solidworks. which software(one of these or another) do you advice for me for working gears contact(please consider accuracy)? thanks a lot for your answer.

@oraldinho

abaqus, i tried in ansys. I could figure out the boundary condition yet. As I dont know whether u have to implemnt PDF eq in ansys. u can try coding in abaqus, and please dont forget to share

Hi Damodharan,

Could you please email the part file and tutorial to me? I would like to attempt to learn it. I tried it in MSC ADAMS. Frankly it was not that good experience. I am proficient in SolidWorks. Thank-you in advance.

Hi DamodharanR16, I am very interested in the analysis of contact forces is seen in this video.

You explain in detail how to do this analysis?

Thank you very much.

@CRIGIDO3D

sorry for late response, I was stuck up with some work!

well I would rather say the force u get in SW has some lose in accuracy as the mesh for RBD cannot be controlled by user(that what I feel personally) Hence their are gona be some approximation always along with some percentage error!!!

to carry out such simulation in SW, just position both gears in place (such that no interface) and goto SW Motion and add contact (more the accuracy, I believe finer the mesh and precis the conti

[DamodharanR16]

@CRIGIDO3D

and precious the contact is analysed !

and then calculate the contact force u will get the forces !!!

anything else let me know!!

[CRIGIDO3D]

@DamodharanR16

Thanks for replying DamodharanR16.

I did some tests but I have some problems. I used the contact  accuracy option in SW motion. The teeth of the gears seem to bounce. I do not get a real movement like your video. I find no reason why this happens. Continue

[CRIGIDO3D]

@DamodharanR16

Because of this, the force contact analysis is wrong because I can not describe accurately the motion.

I attach a video to see the procedure to follow.

thanks for the vtutos are excellent.

@CRIGIDO3D

give me some time!!!

i will get back to u

@DamodharanR16

Ok DamodharanR16 no problem!!!. I await your contact. Thank you for your willingness to help my!

@CRIGIDO3D

I sm sorry CRIGID03D,

Do u have any deadline for this

As I dont have net facility at home I have just relocated to new place!!!

let me know ur urgency I will get back to ASAP or in another 2 week wait is fine with u#!!!

[CRIGIDO3D]

@DamodharanR16

Hi DamodharanR16!! no problem!

I appreciate your concern for helping me. I have no deadline. I'm just very interested in learning about these issues, but not urgent. I hope your help without compromise.

Thank you very much, regards

[DamodharanR16]

@CRIGIDO3D

Iam really sorry, I got stuck in personal probelm.

can u mail me the part file and objective of what u want to do actaully

I am sorry again dear!

please accept my apologies

[Satan0007]

Hi, again.. Only I need prove that magnitude of the force 206 N, can u help me with that? only i ned know like SW calcute to know if is reliable for me to use this tool (SW Motion) ...for me is enough with this example of your two gear! Thanks.

[DamodharanR16]

@Satan0007

well, its now actaully SW, it basically MSc Adams Solver which does the work.

and MSc Adams solver is know for ages for MBD

[Satan0007]

Hi, you say MDB or MBD ?

I just need know like SW calculate that maximum force showed in the graphic. How i can prove with any mathematical expression that valour (mangitude) 206 Newton.

Thanks.

[DamodharanR16]

@Satan0007

sorry, Satan007 its, Multi Body Dynamics!!!!

ok, If you dont mind send me the file and I will port you the Video showing how to do that?

[Satan0007]

How Solidworks to calculate that force?

[DamodharanR16]

@Satan0007

I didnt get you!!

are u interested in knowing the concept (MDB) ?

or else your interested in calculating forces in SW!!

[Fyghosn]

Thanks for this. I've been trying to figure out how to make my gears work properly.
