To study the dynamic characteristics of the oil film in the tilting pad journal bearings, an experimental method was presented to test the dynamic properties(including the oil film stiffness and damping coefficients) of the oil film in the tilting pad journal bearings. The dynamic model of the system was established using the vibration theory, and the oil film dynamic coefficients were calculated based on the absolute and relative displacement data acquired from the experiments. The experimental results show that this method can remove the noisy signals and improve the accuracy of testing, and can also simplify the calculating process.
