Although dynamic balance method of influence coefficient has the superiorities in principle and operation,it does not involve the mechanical essence which causes the unbalance vibrations of rotor,the defect of theory will give rise to fluctuation of balancing results.Through the analysis of counterweight solving process,the relationship between dynamic balancing instability and character of illposed equations was pointed out.Modal superposition method was introduced to describe the influence coefficients, which make the axial positions of balancing planes were connected with influence coefficient equations.A multiblade rotor system was introduced as an example to conduct finite element simulation. The calculation results show that the balancing plane positions have a great effect on pathological characteristic that inheres in influence coefficient equations and the interference of dynamic errors can be reduced by selecting location parameter properly.
