Dynamics Analysis Of Static And Dynamic Unbalance In Rotor System

Rotor machine came into wide use in each field, and, tended to type of high speed and light quantity. And vibration exerts a tremendous influence in the system, serious vibration will result in the calamitous accident of rotor system. Dynamic and static unbalance is one of main reasons that cause vibration in the rotor system, and vibration that it caused, influence the normal operation of system, damage the mechanical equipment. So it is one of the main goals of every research field that how to control system to be unacted on the influence of dynamic and static unbalance, reach original ideal result.Analysis of syslem existing unbalance and getting control equation of dynamics is main intention in this paper: set up the dynamics model of rotor system existing unbalance of static, dynamic, or the two separately, which is reasonable and right; Disuse past idea which only consider system of rigid body, the elastic axis was considered in this paper, in which case analyze system and get its type, and then use suitable equation of Lagrange, draw the general form of the systematic dynamics equation; by analysis of the dynamics method of the past, the analytical method that this thesis puts forward is comparatively accurate.
