Influnce Coefficient of Two-Plane Flexible Rotor Balancing Model Having a Rigid Cylinder

강체 원통을 중아에 갖는 2-보정면 탄성회전체 밸런싱 모델에서의 영향계수

Influence coefficients on two-plane flexible rotor balancing model are derived by using the transfer matrix method. The model has a rigid uniform cylinder at mid-span of flexible shafts. Both faces of the rigid cylinder are used as the balancing planes. Calculated influence coefficients show that there exist the rotating speed ranges which are useless or insensitive for the balancing. Gyroscopic effect and damping are considered in the study and their effects are discussed.
