In terms of the transmission shaft balancing, it exists another problem that the shaft is not looked at as rigid body.When the rotor running at a high-speed ,under the action of unbalance force ,the transmission shaft will bend. It is certainly ideal to balance a transmission shaft as a flexible rotor.However, considering the mass production of automobiles, this method is obviously unpractical. In order to discreasing the flexible deformation, in this theory, the feasibility that double- plane balancing takes method the place of multi-plane balancing on a special place for one segment transmission shaft.

从传动轴平衡的角度来看，传动轴并非刚体，在汽车高速旋转时，由于不平衡力的作用会使传动轴发生挠曲，如果将传动轴作为挠性转子进行平衡当然比较理想，但是不符合汽车大批量生产的实际，为减少挠曲振动，利用挠性转子平衡原理，对于单根传动轴，从特殊位置进行校正，从而以二面平衡代替多面平衡是可行的。
