WebOct 15, 2024 · The dynamic behavior of the rotor-bearing system is affected by nonlinearities arising during operating conditions. There are many studies carried out on the dynamic analysis of rotating machinery with different analytical models. WebJun 28, 2024 · As an output to the rotor dynamics solver, the routine typically has to deliver forces, moments and tangent mass, stiffness and damping matrices. It is expected this entire process can be nonlinear and can be included in both harmonic and transient forced response. Figure 2: user bearing formulation with input/output.
Web摘要： Non-linear frequency response characteristics of a geared rotor-bearing system are examined in this paper. A three-degree-of-freedom dynamic model is developed which includes non-linearities associated with radial clearances in the radial rolling element bearings and backlash between a spur gear pair; linear time-invariant gear meshing … Webmechanical elements that support the rotor, i.e. fluid film bearings and seals.
