Correct, around 4:50 you can see a good view of the tree. No gravity is applied, nor is Contact - where we could apply friction between moving bodies. Friction could also have been set up between mates, but that also was not done in this video. The hand calculations did not include gravity or friction, so the study did not either.
Hi Jack, This comment is not being allowed to be posted as a reply to your post so I am doing it near/above your own. We see stuff like this all the time in our technical support team but it is not generally a bug in the software but an issue in the Motion Study setup itself. There is not simple answer for me to post here for you but I would strongly recommend that you contact your VAR on this so they can help to investigate the cause of your odd acceleration values.
Hello and thank you for your question! You are correct in changing the default outer wall thermal condition could possibly make the model setup more accurate. In this case we left it as adiabatic since it will help decrease calculation time and resources for my very first run of this project, eliminating heat transfer from the outer walls. Also, it is a best practice to keep your flow project setup as simple as possible at first and then begin to add more accuracy and detail to the model and setup. Another thought is that one could also locally apply all our thermal conditions manually to the model in the project design tree and any outer walls that are not specified will be assumed to be adiabatic. I hope this helps!
Hi Tony. Is it possible to use solidworks motion to put force on the top of a piston and read the torque off the crank of a single cylinder engine at a set degree angle of the crankshaft. This way I could plot the torque from a cylinder pressure graph. Could you put up a tutorial if that is possible. Regards Roger
Thank you for the feedback and your question! Though this specific tutorial does not feature this functionality, you will want to add a GEAR MATE to your SOLIDWORKS model (gear ratio is included with this mate type) and SOLIDWORKS Motion will solve this as a rotational coupling between the components. Searching ‘gear mate solidworks’ should help get you started with adding this mate.
Hello, I am currently doing a motion analysis very similar to this. I have set up the motor in the same manner that you show here in the video and the angular velocity graph is correct. However when I create an angular acceleration graph the values are far too high. Have you ever come across this and if so how did you get around the issue! Any help would be great. Thanks
Hey, How can we show the function builder in the animation? Because that tab only shows when we are trying to edit a motor. Can we show it in animation aswell or only in motion analysis?
The Results plots Tony begins building around 6:18 are only available with Motion Analysis - available as an add-in with SOLIDWORKS Premium or Simulation Standard license.
I was trying to do a real torque simulation it seems to be real once and the effect of friction appears till it stops rotation but another one does not, so how can I solve this?
In my case I have a large sub assembly that needs to be rotated, can I use this same set-up even though the assembly is not symmetric like this drum is?
Hi Hello World, This Motion study setup for torque should work even if the assembly is not symmetric. If the model is able to spin it will be made to spin with an applied torque.
GoEngineer does solidworks realize that there is material assigned to the parts? I’m wondering if I need to input a force at the center of mass or not or if it calculates all of that itself?
Hiii sir, your video is too good... from this we can calculate torque required to ratate any object in air..... but how can we calculate the torque if my object is submerged in liquid.... plz reply..
If you need to do this by hand, look up “drag torque”. The increased viscosity of the fluid would cause more drag or shear on the surface of the model, and those terms would need to be included in your calculation. If you’re using SOLIDWORKS simulation programs, use Flow Simulation. www.goengineer.com/videos/solidworks-flow-simulation-webinar-rotating-regions/
7:07 why the torque and power consumption drops down to the zero after 12 sec. ? did you applied gravity and the friction between the joints?

Friction could also have been set up between mates, but that also was not done in this video. The hand calculations did not include gravity or friction, so the study did not either.

How do we calculate the inertia? Is solidworks could calculate it?
Need more informative videos like this
Thank you for the feed back are there any particular topics you would like us to cover?
Great!
I dont know how i hit this video but very useful except one - how to determine Time? I dont get it
great tutorial, can you let me know if the moment of inertia I can find in solidworks in mass properties?
Thank you!
Value of I is calculated in Kg.-m2. And how did you how is the torque results in Nm
Hi 'GoEngineer'
Nice demonstration of SolidWorks Motion - and cool tool for showing hand calculations What's the name of this soft?
Hi there! What is the difference between animations, motion analysis and basic motions?

Good tutorial, i tried and now i know how to , thanks for sharing such a good information
Thanks! We appreciate the feedback. Be sure to subscribe for more great 3D CAD Design and 3D printing tutorials.
Thank you for sharing your knowledge :)
but wonder, do you not have to consider gravity in 'motion study - analysis'?
i need such load characteristic curve like speed-torque and power-speed. Would you help to generate such curves. I may forward you load details.
How did you set up the mates between he frame and the cylinder? I cant the cylinder to rotate

How did you add all the mass data related to the drum? How can we add the load ?
Is it also possible to simulate the friction torque?
its ordinary solidworks? add ins? how can i get it?
Very helpful. Thanks for sharing it.
We are glad to help, thank you! 😊
Helpful.
Thanks for this great tutorial.....................
Is it possible to calculate the moment of inertia of a body composed of multiple masses? Cheers
thanks a lot ...from egypt
You're welcome!
Great tutorial!
How to add gear ratio parameter in it.?

Can you expailn how to calculate torque on kinematic links by considering its length
I want to try it again. Can you tell me the diameter of the drum?
diameter is 354.9 mm and the length is 1000 mm

Is it also possible to take into account the air friction?
Resistance from air is not something SolidWorks Motion could take into account.
Is it neglectable?
I was trying to do a real torque simulation it seems to be real once and the effect of friction appears till it stops rotation but another one does not, so how can I solve this?
Hey can you help me how to dilling animation in solidworks
dear friend. thank you for such a clear ez example for the torque analysis using SW.
Thank you. is such a great start.!!

@@goengineer how can i ask a quiz directly?
Can we find torque output for gearbox??
Hi Ishaan,
While we don't have a video showing that exact situation the steps used in this analysis should also be able to be applied to gears.
Thanks a lot.
Thank you for watching. Be sure to subscribe to our channel.
very good!
k good
goooooooooooooooooooooooooooooooooooooood
i can't find the motor button, mabe if i did, id knew how to do it mostly on my own. but still, i need help to find it.
thanks.
