Evaluation of Forces in Dynamically Loaded Journal Bearings Using Feedforward Neural Networks
Original language description
This paper explores the usage of artificial neural networks to evaluate forces acting in dynamically loaded finite-length journal bearings. Unlike standard numerical approaches, which require solving a hydrodynamic pressure field, the network predicts the forces directly from relative displacements and velocities of a rotating journal to a stationary bearing shell. This practice can significantly accelerate transient simulations of systems supported on such bearings without compromising their nonlinear properties. The proposed method utilises feedforward neural networks, which use a precomputed database of nondimensional forces for training. This database is generated using a finite difference method and supplemented with the corresponding relative displacements and velocities. The performance of the trained networks is also analysed.
