I have a problem to solve this problem. plz help me. I am novice in matlab so please tell me what can I do? Don't become confused, I've made the problem easy to understand. You don't need to know physics
You are an engineer working for a company that has to supply computer equipment for use on a large turbo-prop aircraft. The equipment has a mass of 40kg. You have been asked to provide antivibration mounts such that the response of the equipment to environmental disturbances transmitted through the support structure will satisfy the limits prescribed by the customer.
So basically it means that mass m=40kg is vibrating vertically on a vibrated base.
Condition: P < 1.25 from 0-15 Hz and P< 0.30 from 15-40 Hz.(call the frequency f)
I want to choose 4 mounts in parallel since I think thats stable enough so let n=4
I've given all the formule requred below:
wn=sqrt(4*k/m) wn : natural frequency of the system
zita=1/(2*m*wn)*(4*c) zita:damping ratio
r=w/wn w: forced frequency
The formula for w=2*pi*f
How can I write this program to find the cheapest combination with 4 mounts which satisfies the above condition (Headbang)
