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

    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.
