Multiple Spherical Joint
Multiple Spherical Joint
(OP)
I would like to ask you about one of my problem which I am working on
it related to my M.Sc thesis.
I am simulating a cylinder or a rectangular prism attaching to 12
springs ( I applied LINK for the springs) and these springs are
attached to the body at four point (at each point there are 3 springs
in x,y,z direction ).
My questions are :
- How can I make the SOLID element ( cylinder or rectangular prism) a
constrain to behave as a rigid body.
- How can I define the multiple joints ( e.g spherical joint) at the connection points of the springs to the body in a way that 3 springs can rotate independently.
there are 12 springs which each 3-ones must be attached in one point to the body in x,y,z direction.

RE: Multiple Spherical Joint
Spherical joints: Solid elements have only translational DOF so if you attach beam/rods to single solid nodes, the joint will be spherical automatically.

RE: Multiple Spherical Joint
I am expecting that the result of natural frequencies (6 natural frequencies and their mode shapes match my MATLAB results.
So I would like to ask how can I attach each three links at one node in way that each to be able to rotates about the three coordinate axes independently like independent spherical joint. here is my model!
