Analysis for assembled parts

Sir,

     I have a component which is an assembly of 3 different parts. It's a torsional vibration damper consisting of inner mounting part and outer rim both composed of metal which bounded by a rubber part in between them.

  

     I want to perform a linear static analysis of the assembly with loads applied on the inner part and constraints applied on outer rim. I have meshed each part with perfect alignment with the adjacent part mesh at the contacting surfaces (so that the each node at the contacting surfaces will be commonly shared by the adjacent parts). The parts are meshed with solid mapping of 2nd order quad elements. Also I have checked that there are no free edges in between the parts contacting region. Being different parts (material), I have applied separate property collector to each one of them.

 

What else should I need do to avoid an unconstrained linear static analysis simulation? I mean how do I convey the software (solver) that the inner and outer parts are bound mutually through the rubber?

    Hi,

     

    Use  PBush Elements or CGap element(if gap is very less)
