WebA rotordynamic analysis considers the interaction between the elastic and inertia properties of the rotor and the mechanical impedances from the fluid film bearing supports, oil seal rings, seals, etc. The most commonly recurring problems in rotordynamics are 1. Excessive steady state synchronous vibration levels. 2. WebRotordynamic Open Source Software (ROSS) ROSS is a Python library for rotordynamic analysis, which allows the construction of rotor models and their numerical simulation. Shaft elements are modeled with the Timoshenko beam theory, which considers shear and rotary inertia effects, and discretized by means of the Finite Element Method.
