Bye to all,
I am a student in space engineering and I am doing the thesis on adams, in particular I am reproducing the docking system between the iss and the atv. I have a problem on the assignment of force between two cylindrical bodies that must translate one another.
I first entered a translational joint between the two bodies and then assigned a force of action-reaction between the two bodies, but unfortunately the response of adams in the simulation is a type error:
warning
the supplement has detected a singular jacobian matrix.
this problem may be caused by:
(a) a constraint equations that became almost reduntant, e.g. the model is at a singula configuration or at a biforcation point.
(b) a massless parts in the model
the problem is that by assigning a body-moving force instead of between two bodies, the program turns well, so I do not understand where redundancy is, moreover there is no body without mass assigned. . .
Can anyone help me?
