Sorry for disturbing you.
I really need some help on the regarding topic.
I'm doing an analysis on a comb drive accelerometer.
I use Solid mechanic study and add force -a*solid.rho at x axis of the body load. I attached the pic (noacc) of the result as well
i choose this study to see how much stress can the device received. But from the pic you can see the spring is becoming really twisted and i'm not sure is it supposed to be that way.
next to find capacitance i choose electrostatic and i manage to get it.
all this study is made using Stationary.
but is the stationary study only made in static mode? or is it still consider the device to be moving?
i already stated acceleration, a in parameter.
Now, i wanted to check its modal analysis.
when i choose this study, it automatically gives eigenfrequency and frequancy domain steps.
From here where can i get the resonant freq?
i could not get the any result for the frequency domain when i tried to get displacement vs freq result. see simresult picture. i thought the curve should be like in pic freqresult
i don't know if i set it wrong somewhere.
please help
