Ball Joint in Mechanica

Is there any turn around for Ball Joint in Mechanica?

I searched the forum, but couldn't find, All I see were related to Mechanism

I need to do a validation on the steering arm, which transfers the load from the Ball Joint to King Pin.

Pls anyone show me some light to simulate the Ball Joint or how this mechanism can be handled

It depends on exactly which component you want to analyse.

Do you care about the stresses within the ball joint itself, or only a component that it's attached to?

Usually, I think a weighted or rigid link, or even a Total Load at Point, should be sufficient to apply the loads into the component under analysis.

I forgot to give few info,
I'm using Creo1.0 on XP I'm all the way new to it.

I'm not sure how the advancements actually work like rigid link(DOF)

And answering to your question,

My concern is to study only the Steering Arm, but I want to simulate the Ball Joint as well.

I've directly applied the load to the center of the Ball Joint and excluded the outer cover, but my results seems to be multipled(I mean load on steering arm seems to be) So I like to simulate the Joint now to get closer to real.

Your first approach sounds like the right one to me.

How exactly have you applied the load to the ball joint? Can you share the model, or at least screenshots? What makes you think the load is multiplied?

When you say that you want to simulate the ball joint, do you mean that you want to simulate the kinematic nature of the joint?

One method that quickly came to mind is to represent the shaft (with the ball on it) as a 1-D beam element and use beam releases to capture the nature of the ball joint (all translations are lock and all rotations are free). You can then use weighted links to tie the ends of the beam to relative locations in the model.
