Abstract A theoretical study has been carried out to determine an approximate analytical description of the fluid film force of a symmetrical rigid rotor supported on two finite‐length lubricated journal bearings. The analysis has been conducted assuming the Warner solution for the pressure field. The analytical approach to studying the behaviour of a system is more effective than numerical investigation, and makes it possible to cover not only an individual system, but also the whole class to which that system belongs. Furthermore, the model proposed allows quick analytical determination of the stiffness and damping coefficients.
