Hi,

I am trying to do simulation of air horn diaphragm,

Inputs:

Diaphragm dia and thickness and material property.
Input pressure on diaphragm.

Output:

Max deflection of diaphragm.

Kindly provide me steps involved in simulating said diaphragm.


Thanks in advance........

Hi

you could run "solid" but be sure you have a few elements acrss the tickness, attach fixed the circumference and apply a boundary load. Or you could try with shell physics, it solves quicker

Good luck
