Creating joints in hypermesh

Altair Forum User

Dear Altair-Team and community,

I build a 1D mesh of a spaceframe and I am just trying to model the wishbone (lila) to the steelframe (yellow).

I would do it with a revolut joint but I am not sure how to realise this.

I have the axis and two fix points.

How I adjust a joint right?

Thank you for helping!

Hi,

You can create a local coordinate system to adjust the orientation of the joint.

Create temporary nodes and create a local system. Use this system to orient your revolute joint.

Hey Prakash,

thank you for answering.

To understand the joint I created an example based on your Post, but I have a problem with the revolute joint.

I wanted to assigne a joint between a lever and holder. So I try to:

1) Select two nodes

2) Oriented along the x-axis

3) Creat (part of the holder)--> joint appears

But when I start OptiStruct in HyperView the joint is not there and there is no connection between lever and holder.

What I make wrong?

Regards

Andre

Hi,

Thank you for sharing the file.

Joints are not visible during postprocessing, but I see that there is no displacement at all in holder. I will check and update to you soon on this.
