The invention discloses an influence coefficient dynamic balance method on rotating machine with multiple plane, multiple-points and multiple revolving speed shafting. The influence coefficient dynamic balance method on rotating machine with multiple plane, multiple-points and multiple revolving speed shafting comprises the steps that 1, designating a shafting balancing revolving speed point, balancing planes and numbers of measured points; 2, an initial deflection value of a spindle and an initial vibration value are measured under a slow revolving speed of 300rpm; 3, a vibration response of the measured points on a bearing after trial mass is conducted on a plurality of balancing planes on the shafting; 4, the minimum value of the residual vibration amplitude epsilon of all vibration measured points after the rotor is balanced is set as a goal, a vibration response vector equilibrium equation is established, and a size and angel of a balance weight Q on the unit shafting are obtained; 5, the vibration value of all vibration measured points are read, the above steps 2, 3, and 4 can be repeated once the value is unsatisfied. The influence coefficient dynamic balance method on rotating machine with multiple plane, multiple-points and multiple revolving speed shafting has a overall consideration on vibration with multiple plane, multiple-points and multiple revolving speed shafting, and a seesaw phenomenon in the traditional dynamic balance process is effectively avoided.
