Figure 10: Statistical results of the number of AFPs of rotor unbalance of each disc in the simulation of g4.4 using #40 point as one of the required measuring points and a 0.1 nm resolution: (**a**) results of unbalance amplitude; (**b**) results of unbalance angle. Simulation results for h1.4  
In this simulation, #10, #20, #30, and #40 points are used, respectively, and the other \(m+n\) measuring points are at the discs and bearings. \[SDA\_M1_{h14}=\left[\begin{array}{ccc}\begin{array}{ccc} \begin{array}{ c}\framebox{21.67}&\framebox{176.86}&\framebox{178.86}&\framebox{179.80}\\ \framebox{119.47}&\framebox{7.69}&\framebox{172.06}&\framebox{179.22}\\ \framebox{142.30}&\framebox{139.97}&\framebox{136.16}&\framebox{163.97}\\ \framebox{140.05}&\framebox{83.30}&\framebox{170.82}&\framebox{12.68}\\ \end{array} \right] \tag{10}\]
