How will we handle this when use shell modell from the mid surface?

Hi Arion, I'm not sure if you'll see my message, I hope you do, but I'm modeling a jaw opening device for a dairy cow (for tooth inspection), and it uses a lever arm connected to small driving spur gear, which is connected to a larger driven spur gear, for mechanical advantage. I also have a crank wheel sandwiched to the small drive spur gear and a double pawl (one for driving and one for locking) so that I can crank the lever arm through an upwards then downwards arc, 5 times to gradually open the cow's lower jaw. I am designing it in NX2306, and wish to do a motion analysis on the assembly when it's interfaced with a 3d model of a cow skull upper & lower jaw assembly. Do you think you may be able to help me set-up the motion analysis? Thanks, Scott

The calculations for bending stresses use the leg length not the throat size. Welds are analysed based on the assumption all loads are transmitted in shear. You need to use the throat length in these calculations not the leg length.

Thank you 👍🏻

Thanks for uploading the video, your channel is very educational!

Singularity is such a bad case, it happens way too often. Also, it is always unpleasant to explain to people why the simulation is showing high stresses, but they shouldn't be worried about it...

Good Job!!!

Thank you for those detailed NX Motion videos. I have a question for you and only you can answer this: I have a mechanism with few joints lets say and I want to minimize the load at the joint 3. So, I want to iteratively move the X position position of the joint from 50 to 150 mm 1mm by 1mm and compute the simulation again and again and find the least resultant force among them. How can I do that? I can not record the results as an expression so I cannot use the "goal seek" function of the excel of NX. Thank you!

We are adding time dependent load. Then why static simulation? And stresses shown here is at which second?

Very informative video Please make more videos.

Very informative video.

Great help, couldn't find this anywhere else

Can you provide some details on how did you do simulations

you are a genius.Thank you very much

Hi, do you have any idea how to calculate friction forces in the bushings? I would write a function for resistance torque based on the radial forces in the friction, but i dont know how to extract them, i cannot even apply sensor to measure these forces.

Добрый день очень прошу подскажите. У меня стоит следующая задача- есть рейка со спец профилем нужно прокатать относительно нее цилиндр и получить профиль зуба. Результат прокатки я должен использовать для нарезки зуба. Прошу покажите как именно прокатать и получить шестерню.

Thank you very much!!!

Nice work.

Great content man, can you make a video on how to implement a PID controller in Simulink and run a cosimulation in Nx motion? I've to do it for a 6 DOF robotic arm and I've started using motion for less than 2 weeks so I'm kinda lost

plz share the files.

Ver good content mate!

good !

Best lectures!

Tanks

That's great

Good job

Mate could you tell what is actual throat size and theoretical throat size. Is it 6 mm.

Sir could you tell what is the weld throat size and weld size is it 3mm or 6mm.

thank you for sharing

Thanks for NX video. I really liked the explanations that you provided for how to validate FEA results with theoretical calculations. Please create more videos with such theory and interpretation with the results obtained from FEA. THANKS a lot!

Your video is useful to me. Thank you

Very helpful bro!

Hi there, I tried to simulate a similar model but with the model in half. I expected the result of reaction force in z direction (x 2) to give the same answer as if I had a complete model. Unfortunately that is not the case. Any clue where the mistake could be? I cut the model with xz plane, so I created on the corresponding faces boundary contraints with fix translation in y-direction. Another question... Can I apply the reaction force (Load force in z-direction) in an another solution to double check if it give me the desired diplacement? I tried but didnt get any result. I would appreciate it if you could give advice or show a short demo on it. Thanks.

خيلى ممنونم

Hello! Can you link us to pdf tutorials of this kind of example (specifically of application of movements/motions)? I really appreciate it if you could :) Best regards and thank you very much for this video and explanations!

on the pulse!

سلام وقت شما بخیر ممنون بابت ویدیو های خوبتون. اگه یه لطف کنید در مورد کلاس آنلاین پاسخ بدید که آیا برگزار میکنید یا خیر .ممنون میشم.

Simply, amazing! <3

Very good. Nicely explained.. Keep it up...

Could you PLEASE replace Shaft with a Bearing ? I would like to understand how the Bearing Internal Clearance is affected by pressing the bearing on OD hub

Thanks. Will there be an NX Motion 3 as well. I would like to see that as well.

Please share the model here or through googledrive

Good work. Please tell us which version of NX you are using. Also share the model here. israrullah@gmail.com

Like it ! Thank you for sharing this...

Yes, if Shaft need to transmit 600Nm, I would like to see please if possible, how much Ring need to move

NX Starts at 11:00 ;D
