I would like to conduct a gauge optimization. In the optimization I intend to realize, I would like to minimize the vibration acceleration
I would like to define the following constraint
- Let the acceleration value be lower than 0.125g (1.23 ms-2) at a frequency 3 times the mod frequency
- also, I would like to a define the vibration displacement in terms of natural frequency using an equation which was attached.
- finally I would like to define the equation as a constraint
How can I define these constraint ?

best regards, thank you for quick response
