Through analysis the reasons influencing measuring stability have been found out, which are the flexure strain and structure resonance produced by the transmission axle under the function of the gearing-in force of the reduction gear.

• 虽然与传统的测量方法一致，但经过理论分析，得出了这种测量方式机械结构影响测量稳定性的原因，即传动轴受减速器齿轮啮合力作用産生的弯曲应变和结构谐振对测量精度影响最大。
