vincoli adams

[Giorgio84]

Hello, everyone is a day.
I need help on a thesis project I'm doing in adams view.
I just use this program, and I can't put any conditions on the constraints.I have the problem of imposing angular shift to a motorcycle chassis (fold condition in the curve). for now I tried to use a cylindrical guide, then loading a spline with all corners of fold. My model, however, "falls" (poor pilot...), that is to say, it does not rise (as it is "written" on the spline). Surely there is some background error....you know how to help me? ? ?
Thank you in advance all those who will help me.... hello! ! ! !

Hello, Father,

impose angles in the sense that you created motions on the bond?

If yes, and what you want does not happen, maybe you are in such situations (from "inexperienced"):
1- Motion is not properly defined. verify that the spline is considered, for example, for the analyzing trait that works (which does not fall), verify that the imposed spline and created movement coincide, you know the binding reactions on such motion/motions, etc.
2-The model is hypervincola and adams eliminates the bond (even motions are constraints) and then you change the cinematic chain you have built. this adams does it at the first step of integration, you can see in the message of the solver, which wins has taken away and understand if this is the problem. in this case create a cinematic chain at least isostatic (if not labile).
