The invention discloses an anisotropic rotor holographic dynamic balancing method based on equivalent
initial phase vector. According to the method, the holographic spectrum principle is taken as the basis, vibration data in two directions are taken into account and are subjected to data fusion, so the anisotropic characteristic can be completely formulated, and the balance fault diagnosis is facilitated; furthermore, the rule of
angular momentum conservation is utilized, a holographic spectrum
ellipse is converted into an equivalent rotating frequency circle, the equivalent
initial phase vector is taken as the characteristic for unbalanced vibration, and the requirement on fine balance is met. Through the equivalent
initial phase vector, the defects of traditional initial phase vector on describing the amplitude of unbalance and phase position caused by
anisotropy can be eliminated, the unbalance characteristic can be accurately characterized, and the spatial dynamic property of a rotor can be truly indicated. Therefore, the anisotropic rotor holographic dynamic balancing method based on the equivalent initial phase vector, provided by the invention, facilitates improving the accuracy and efficiency of on-site
dynamic balance, so that the operating precision and service life of a
rotary machine can be effectively improved and prolonged.
