optimisation of component performnce in modal analysis

Luca Campello

good morning every body

i'm preforming a modal analys of this system. it consist in a sheet (red component) clamped at one edge with a support (yellow component). I'm wondering whether it is possible to optimize the shape of the yellow component in order to have torsional mode (2^ resonance) and bending mode (3^resonant) with a equal or same magnitude order modal partecipation factor? 

for modal partecipation factor which response variable should i use?

many thanks in andvance

Hi Luca Campello,

In modal analysis, you can define Frequency and Mode shape as response.

Modal participation factor as response is not supported yet in Optistruct.
