A New Dynamic Balance Framework Based on Blind Source Separation under Multiple Fault Conditions

Table 10

Rotor balancing results using convention ICM with external force.

Run state	At condition weight (g)/angle ()	Vibration amplitude ()	Phase angle ()	External force
Original	—	43	26	T5R6
Trial	4.9/135	75.8	24	T5R6
Balanced	6.5/315	8.5	129	T5R6

Final vibration amplitude reduction %: (43–8.5)/43 = 80.23%. Final amplitude error of balancer vector %: (19–6.5)/19 = 65.8%. Final angle error of balancer vector %: (278-275)/275 = 14.55%.
