Relation between volume fraction and modal frequency target

Question

Hi everyone,

Trying to figure out how much volume fraction has to be given for meeting a specific modal target frequency of a automotive wheel while performing topology optimization.

Just trying to find out the relation between volume fraction and modal frequency of wheel (wheel weight is 13 kg). 

 

For Example

Target modal frequency of wheel should be above 400Hz.

For meeting the modal target (above 400Hz) how much volume fraction value need to given in a single shot so that the modal target is met, in topology optimization of wheel.

 

Thank you  in advance.
