- Hello,
Welcome to my next tutorial, In this video I would like to show you how to prepare model, create mesh and define boundry condition to create helical gear simulation. In this tutorial I made analytical calclulations of bending stresses at the root of the teeth. We could do this by the probe option but I wanted to check stresses at single node and how they change across the simulation.
Enjoy :)
Hi，Can you provide some teaching on the geometric processing of this model about these slices？
can you make the same video for a normal spur gear with shaft please?
actually the process will be the same but the mesh would bo very big which may lead to time consuming analysis.
It's very nice to see how this channel is progressing! Great video, it's very helpful and approachable. Hope to see more, cheers :)
May i ask, what type of the contact you use between the tooth?
can you please explaine how did you make those slices on gear tooth
How can we determined angular displacements i. e. if one gear is rotated by 1 degree than due to deformation the other gear rotated by greater than 1 degree. Angular deformation = theta2-theta1 where theta1 is input gear rotation angle and theta2 is output gear rotation
Very helpful! Nice!
thank you so much, i was struggling a lot with my simulation and with your tutorial i finally finished my simulation
Hi, could you please tell me if theres any way to change the contact ratio of the gears in ansys?
Hello sir , I followed the same steps but I am getting error.
An internal solution magnitude limit was exceeded
I tried this analysis on spur gear. But it shows converge error and solution exit. If you give your mail, I will send my file
Not enough constraints appear to be applied to prevent rigid body motion. This may lead to solution warnings or errors. Check results carefully.
Getting this error
Please help
I imported an IGS file from solidworks
And followed all the steps of your video
But the gears are moving apart during analysis
It's probably due to incorrect possition of the gears. Try to position the teeths as close as possible and then in contact option try to set "adjust to touch", let me know if it helps :D
Hi Can we find out mesh stiffness of gear and plot a graph between angle of rotation and mesh stiffness, if yes can you explain the procedure?

Thanks for the video. How long did the simulation take? what is the ram of the pc? I ask because I am working on a similar simulation and I want to know how feasible it is to give a complete turn of a pair of spur gears with shafts and bearing supports for my pc that is 16 Gb of Ram
It took somewhere around 4 hours on PC with 4Gb of RAM to calculate the analysis.
Good demonstration and it was satisfying to see it match so closely with the analytical calculation... But what were those slices... Many people has asked about it...
Could you please explain Or share some link for that
The slices was the parts that was made to make a mesh more dense in some parts of the gear.
Can you show the graph of force generated at contact points
2. Instead of moment if we want to apply load on flank (line load udl) can you show in simulation?
Hi, thank you for interest in the movie.
According to your question I can't show to the graph or how to apply load on a flank because I don't have this analysis on my PC anymore.
@@allaboutfea4790 not in this simulation...but by taking any other spur gear can you show analysis where a line load acts on flank...at some angle?
@@prof.onkarsalavi7143 to be honest with you the only difference is that you have to add a foce to the flank/face. There are some videos on YT on how to do it.
@All about FEA: Hi. I am actually doing a similar thing but with Involute Splined Shaft. But unfortunately the model is not getting solved. So I was wondering if you can share your model. It will help me a lot. Thanks.
Hello, I don't have this model anymore.
@@allaboutfea4790 Hello. Is it possible for you to check my model and help me find out where I am making the mistake?
I can share with you my geometry and FEA model over your email id. It will be a great help for me. Thanks in advance.
Very nice analysis.
thank you , that is great
I want to find contact stress . But not coming
First in "analysis setting" you must turn on the "contact stress". Then you can extract the contac stresses in the results.
Excellent video. One question, how you do it using a hypoid and bevel gear?
What do you mean?
@@allaboutfea4790 I'm trying to do a simulation about a bevel and hypoid gear but I don't know which complement should I use and how to do it.
excellent...
Thank you for your work!
I have also the same problem, I would like to plot gear mesh stiffness. Is it possible??
Thank you so much. I need such simulation to my diploma.
Super, cieszę się, że mogłem pomóc :D
@All about fea
I was doing same simulation from past 2 months but While simulating for bending stress analysis I was unable to find the bending stress and error occurred . So can you help me !!
Hello, thank you for question, but what error actually occur? Is it something with analysis or maybe you analitycal calculation don't match the FEA analysis?
All About FEA I am not able to get bending stress in ansys
All About FEA Can you help me to solve that ?
@@kishanpatel651 but I still don't know what is your error which makes it impossible to check the bendind stresses. Is your analsis coverge?
Sir can i mail u the my ansys 19.2 file along with the research paper i am referring ?
