Hello,

I am new to Ansys workbench. I need to analyse Rigid Body dynamics using a cross of two Rigid links attached to flexible D shaped 2d sketch. The dimensions which I have are just centre of gravity of these two rigid links and Principal moment of Inertia.   Can you guys please help me on how to proceed with it?

Regards,
Bruce

Hello Bruce, wellcomme at CAD.de.

For Ansys we have also a special board, were your question would be better placed.

Do you mean how to connect the 2 rigid bodies to the D-frame ?

There is in Ansys a gap element for such cases.

If the connetion ist flexible too, you may use a spring element.

Hello Klaus,

Thank you for your welcome. My problem is as stated below.  
A two-dimensional problem with a D-profile fender (bounding box 0.1 x 0.1 m, "circle" of the D has a diameter of 0.1 m, wall thickness 25e-3 m, m = 8 kg/m). Use the Neo-Hooke material model (C10 = 1.4040e6).
Attach a cross of two rigid links with point-like masses at its ends to mock a 6 DoF model. The center of gravity is at x = -1.364601093 m, y = 0.0, z = -30.408958e-3 m, measured from the center of the flat side of the fender. The total mass is 79.2 kg, the principal moments of inertia are Ix = 8.8205288622  kgm^2, Iy = 31.4882460458 kgm^2, Iz = 36.6609663086 kgm^2. I was able to create D fender with required dimensions in ansys workbench but I don't know how to create rigid links.
Can you guys please help me on how to proceed with it?

Regards,
Bruce
