全息动平衡法融合转子系统测振截面中两个相互垂直方向的振动参量制定系统的配重方案，以保证各测振截面周向各方向均具有良好的振动；然而全息动平衡法以初相矢为平衡目标制定的配重方案有时会出现不能保证测振截面周向振动的情况。通过各向异性转子系统失衡和响应关系的分析研究，发现初相矢与转子系统的失衡量之间存在线性映射关系；在原始失衡与配重截面存在轴向位置差异的条件下，受系统降维等效的影响，失衡和响应“椭圆映射”关系中的时间耦合问题是影响初相矢平衡方案不可靠的一个主要原因。在以上分析的基础上，提出一种相位补偿方法修正并优选初相矢对应的配重方案，以消除时时间耦合问题的影响；通过仿真试验，现场案例分析，验证了相位补偿方法对应配重方案的可靠性。

Through fusion of vibration information collected from two mutually perpendicular radial directions, the balancing scheme obtained by Holobalancing method can ensure the overall vibration level at any radial directions. However, there are still some deficiencies in the Holobalancing method when the initial phase vector(IPV) is used as the balancing object. According to the analysis of the relationship between mass unbalance response and the anisotropic rotor-bearing system, it is found that the unbalance mass is linearly mapped to the IPV. If the axial position of the original unbalance mass is inconsistent with the balancing planes, the time coupling problem brought by the elliptical mapping relationship between mass unbalance and system response is the main reason that makes the balancing scheme unreliable. A phase compensation method is presented to eliminate this problem through a balancing scheme optimization process. Finally, the reliability of this method is verified by simulation experiment and case study.
