Hello,

I want to know how to integrate kinematic conditions in Hypercrash

    Hi,

     

    In HyperCrash, Goto LoadCases>> Boundary conditions.

    I mean the connections between the different parts.
    sliding connection, revoluted...

     

    Thank you

    Okay, sorry I thought you want to create kinematic boundary conditions.

     

    If you want to create contacts go to LoadCases>> contact interface.

    is there a worshop where we can define the kinematic pairs ( revolute, prismatic...)?

    You can apply cylindrical joint using HyperCrash, 

     

    If you are specific about re volute joint, what you can do is constraint using kinematic BC and leave the rotational DoF of desired direction.

    I want to apply the cylindrical joint, but I have no idea about the parametres that I have to define such as:

    sttifness, critical damping factor...

     

    Thank you

    Hi,

     

    Cylindrical  joint in RADIOSS behaves like a rigid body.
