Engineering Design of Machines with Rotating Members

Popis výsledku v původním jazyce

The aim of the paper is to acquaint the reader with the design of the incorporated absorber to the vibration machine with rotating members, which makes the reduction of the vibration of the machine to a minimum possible. Vibration in a machine has two effects. First, the very high peak accelerations can mean that the effective weight of the vibration machine increases several-fold, and this may cause its destruction. Secondly, people near machine feel these accelerations, which can be uncomfortable or even dangerous. A vibration absorber is used to protect the machine from steady-state harmonic disturbance. The present article will discuss a method of vibration control LQR (Linear Quadratic Control) for structure using the vibration absorber without damping. Depending on the driving frequency of the original system, the absorber needs to be carefully tuned, that is, to choose adequate values of absorber mass and stiffness, so that motion of the original mass is a minimum.
