Spherical bearings/Rod ends in asemblies 1

[GTMule]

Still working on modeling the rear end of a race car. Well, all those suspension bits are connected with rod ends, and balljoints. Modeling all of this is not a problem, but, I cna't seem to get it properly constrained such that I can move it all around, and check for interference at different levels of suspension travel. BAsically, wht's happening is that, when I use "move component" with the interference detection set to keep the parts form existing in the same space. This works to some extent, but sometimes, it fails, and the sphere part of the bearing will jump out of the race. There's probabally some simple solution to this, but I don't know what it is. I'd appreciate any help on this, or a lonk to a site explaining it, or....something

Thanks

What I have done in the past when working with ball joint rod ends is to create a sketch point in the center of rotation for the joint. I do this for both ends, and just mate these points Coincident. This gives me the rotational freedom that is required. "The attempt and not the deed confounds us."

Do you have Flexible assemblies turned on vs rigid?

SO basically your joint doesn't rotate in the housing? That's fine, I'm just wondering. I guess your rod end basically is just modelled as one piece, the just moves around?

Thanks,

Try using a Symmetric mate in you assembly of your spherical parts.

Sometimes, something like that happens to me.

When I am modeling mechanisms and activate the interference detection to simulate the kinematic and its limits, sometimes there are components jumping out of their interference restraint (but maintaining their mating restraints).

I think this is caused by to much speed on the mouse during simulation. Maybe, to catch the mouse, SW make big jumps on the iterations and skips those that would make it stop at the interference.

Try to do the simulation moving the mouse gently. A more complex simulation requires a slower mouse movement.
