Rob, Thank you for posting this overview! I am working on an assembly that is a little less complex than yours, but Inventor keeps telling me the model is over-constrained by 3 degrees. I have 3 hydraulic cylinders in the assembly. The errors seem to be related to the cylindrical constraints between the rod and tube, and the cylindrical constraint's Inventor automatically applied to the cylinder pins that connect it to the structure. Any ideas?
Hi, this really helps me what to do to find the unknown force of the hydraulic. When I started to run the unknown force, there's an error that says "Impossible to assemble the mechanism, due to joint stops or locks defined by the user." I am not sure what locks it means but while doing the design I can just move the design fine no locks or whatsoever.
hi guys i would like to ask , what mean U_imposed which usually give torque around in a joint and it is in N.M ,,,can i consider this as torque applied ,,is it input or output due to the motion of whole mecghanism ,,,appreciate any one input
Hi, Thanks a lot. It gave lot of help in understanding the Dynamic Simulation. I have developed one model which have 2 Cylinders which are suppose to push one door up. But when I start unknown force application it says that unknown force "To use unknown force functionality , the mechanism must have a single degree of mobility. Currently it has 5 d.o.m.'s. In the joint properties dialog box , "Lock" d.o.f.'s." I am not in a position to understand. Can you help me please on this?
Hi Prasad, I don't think I could properly explain the answer to your question in these comments. There is some quality information in the Autodesk Inventor wikihelp (help.autodesk.com/view/INVNTOR/2014/ENU/?guid=GUID-5D433007-2D3C-41C9-8647-83CA4514D1B7) along with some good tutorials. When I teach a class on Dynamic Simulation I use "Up and Running with Autodesk Inventor Professional 20XX Part 2 - Dynamic Simulation" by Wasim Younis. Its an inexpensive book and can be found on Amazon.
Hello Robert, Thank you for your kind help. This link will surely sort most of my problems. I am looking forward to go through all the information you have sent. Thank you once again.
means u have 6 degrees of freedom..3 for translation and 3 for rotation like every body has...what u have to to is to make sure your body can either rotate about x,y or z- axe or u can move the party in xy,xz or yz layer...just one rotation or translation allowed..
Rob, after the FEA simulation you did not mention that the part failed at 575 Mpa and 0.4 safety factor. I realize you are just doing dynamic simulation training, but you should mention that it failed as an aside.
Hey man...so I have a project that i want to run by you... I have the sketches and measurements. It shouldnt take you long.... Anyway...let me know if you are interested! I really want to get this project off the ground and could use the help. I can also pay if you want that..Please get back to me! Thanks.

Hi,
Thanks for the Nice Simulation and FE Analysis, The presentation was really fantastic and guiding into very much detail analysis.
Great video!
Thanks a lot!
Nice overview!
Great, Thank you very much, Sir!

Nice presentation! Is the own weight of all the parts also considered in the calculation of the reaction force in the cilinder?

very nice
Where can you download the truck assembly?
How do you use navigation button?

Thanks for this. How can I have the inventor native file?
Great video! Is your cad model available for download to replicate your steps on our own
Hi Sunil, we'd be happy to help you replicate your steps! Give us a call at (877)311-6284.

Yes, gravity is a factor.
could describe the features of your computer please?
They have company servers
please can i get the drawings so that i can also try my hands on it?
