Herringbone thrust bearings (HTB) are widely used for their high load capacity, low friction, and good stability, making them ideal for various applications like turbomachinery applications and automotive engines. In this research, the effect of changing the groove depth, which affects the thickness of the fluid film, was studied on the dynamic coefficients of the HTB up to the second order. This investigation is really important in studying the dynamic behavior of the rotor-bearing system. The Reynolds equation was solved to obtain the performance parameters for the HTB. Then, the infinitesimal perturbation method was used to obtain the perturbed Reynolds equations up to the second order. The Finite Difference Method (FDM) was used with the Successive-Over Relaxation (SOR) technique to obtain the stiffness and damping coefficients of the HBT. The variation of the first the second order bearing coefficient with the change in groove depth was studied. The results showed that with increasing groove depth, there is a decrease in the dynamic coefficients of the herringbone thrust bearings. These results can be further used in studying the dynamics of rotor-bearing system for machines operating at high speeds.
