Investigation on the influence of unbalanced shaft component in gearbox on displacement using the Newmark-β method.

In addition, Fig 12 and Table 6 show a decreasing trend of displacement amplitudes by ±0.098 mm, ± 0.079 mm, and ± 0.054 mm as the load position shifts from 0 0 –0 0 to 0 0 –90 0 and then to 0 0 –180 0 , respectively. 4.3 Motional orbit To evaluate the influence of the unbalanced mass position on the rotor’s motion trajectory, a series of experiments was conducted at a rotational speed of 2000 rpm.
