Hello Mr. Singh, I guess direction of vibration like vibration in vertical plane or other is also required, However, I will assume that the unbalance in the fan or rotor creating vibration in vertical direction, second assumption unbalance is acting from the centroid means no rotational vibration. In that case, we can employ an absorber using a cantilever beam (made by any metallic strip) with a tip mass. The natural frequency of this system will be 46.66 Hz as rotation rpm is 2800. How to do it? using freq=(1/2pi)* sqrt(k/m) Hz, where k = beam stiffness k = 3EI/L^3 ..based on the stiffness computed you can choose a mass that will result in 46.66 Hz freq. Now where to implant this device. You can place it on any vertical wall of your cooler. I tried to answer your query, there may be CHANCE STILL IT IS NOT CLEAR TO YOU... Please send me picture of your cooler on ashishpurohit1@gmail.com
2:47 why the secondary syatem vibrates at high amplitude?
Why the vibration of primary system is reduced?
How to reduce vibration of cooler which is supported by four clamps? 2800rpm ,50hz,230v.
Let's see practical engineering.

@@ashishpurohit9138 Glad 🤗😀😊to read to reply ,would revert back to you with necessary details as soon as possible.
Thank you for your consideration.
@@ashishpurohit9138 Great!!!
Sir, which book do you preferre for vibration?
v p singh
Bhaiya plz or video banao holzer method or stodola method pr....plz....Mera Monday ko vibration ka main exam h ....plz.plZ...plZ
Reply as you read.
Centrifugal pendulum absorber please explain
Okay Mohit...soon I will do it
Thank you sir plz do it before 8/12/17
Thanks Sir
Bhai app loog hindi ma video ku nhi banata english ati to tumhara video ku dhakta aur foreigners to dhakanaga nhi plzz bhaiya hindi ma samjaya karo
