Bushing joint for springs in 3-directions?

[GMarsh]

Hi,

I would like to connect surfaces of two bodies with springs in 3-directions (X,Y,Z) in ANSYS software. As the surface normals lie only along Y-direction and that a spring accepts stiffness only along its longitudinal axis, I am wondering if I can use Bushing Joint instead and define stiffness in K matrix in 3-directions. I am considering to use high rotational stiffness so that rotational DOF of Bushing joint will not have effect.

Thanks in advance for your advice.

Regards
Geoff

Hi Geoff,

I don't know bushing joints, sorry. I think you can use a matrix27 element, which can be defined as mass, stiffness or damping matrix, and can connect two nodes with 6 dof.

Hope it helps (though I have a little doubt )

Hi Orel,

Thank you for the reply. I had a try with Bushing joint. It worked! I have not tried Matrix27, but my colleague said its function is similar to that of bushing joint as far as assignment of stiffnesses and damping are concerned.
