description The invention belongs to the technical field of dynamic balance, and particularly relates to a multi-segment shaft joint rotor dynamic balance method for a small aeroengine. According to the invention, based on a mechanical vibration test method, the vibration of a rotor is transferred to test on a stator; the rotor is assembled to a casing according to the assembly sequence; two support shafts are led out through two mounting sides of the casing and supported on two brackets of a balancing machine; when the rotor rotates, the vibration value is transmitted to the casing, and is transmitted to the balancing machine through the support shafts led out on the casing; in order to stabilize vibration measurement, a selected mounting side needs to have a centering and positioning structure, and the positions of two mounting side should be as far as possible, so as to be beneficial to the separation of unbalance of two fulcrums of the balancing machine. The method provided by the invention incorporates all basic inf
