Hello Everyone
I have recently switched from ProE to Solidworks. I am quite familiar with Solidworks from previous employment but not with COSMOSMotion.
I set up a trial assmebly to check how COSMOSMotion worked compared to ProE Mechanism. It consists of 2 bars with hole centers of 1000mm and ahydrauliccylinder representation to make it move of 600mm closed length. On the moving arm there is a 100N force (vertical down). The analysis finishes when the moving arm is horizontal to make checking easier
I have a results graphthat displays the force at the base of the cylinder.
The problem is that the predicted force is correct at the start but is approx 10% low by the end of the analysis.
Now the really weird thing is if I start the analysis from the point that it finishes i.e. with the arm horizontal, then the starting value is correct.
Initially I had a number of redundancies so I re-mated it so there were none and the problem remians.
Any insight would be appreciated.
Cheers
Tarquin
p.s. I will try to post a couple of pics of the assembly and graphs.
