vibration transmissibility

Recommended Posts

hi admins and moderators

I have a vibration isolation model, as below picture, blue, green and pink part represents shaker table, specimen and constant mass, respectively

I would like to assume blue and pink component as rigid how to perform it ? and Do I need to assign a material card to these components?

For rigid element no need to define property. For constant mass component create CG and connect Specimen/Constant mass component with RBE2 to the CG of constant mass. You could use CONM2 for concentrated mass.
