Hi Everyone,
I am new to the dynamic simulation environment in Autodesk Inventor, and I am having issues with constraints not being properly converted over to joints. I have attached the files I am working with for reference. I would really appreciate , if anybody can open the assembly files (cossack3.iam) and let me know what am I doing wrong.
Hi Sandhus,
Your mechanism is overconstrained.
As a matter of fact it has 2 degrees of redundancy.
It is a message error, but often (keeping clearly what happen) can be ignored.
If in a status of forces and constrains you have more constrains that necessary the system become indeterminate.
In your case the visive dynamic simulation will works but the distribution of forces and moments can be altered due the redundancy.
Automatic conversion of constraints is good because is fast and do for you a lots of work..but as all the thing done quickly needs often to be adjusted.
Your cylindrical 8 for example has already a reduced degree of freedom due the other joints inserted.
So you have to eliminate the redundancy.
You can do this bye release the unecessary degrees of freedom eliminating constraints, changing the dof of joints, eliminating joints and repositioning with onother solution..etc
In this case for a quicker solution i have inserted correct joints,and converted some, weld parts...etc
Attached i have attached the assembly,done with 2014, i don't know your release and if you can open it.
I hope that it can helps you.
