Rotordynamics Analysis (RDA)

RSR is focused on providing validated, multidisciplinary modelling and simulation results for the accurate determination of the vibration characteristics (rotordynamics) of engineering systems. RSR's RAPPID™ software integrates stress, thermal, contact mechanics, multibody 3-D rotordynamics, flow network, and multiphase/multispecies CFD for advanced transient simulations of rotating machinery in 2-D or 3-D.

Rotordynamic Coefficients: Bearings, Seals, Dampers, & Wheels

Advanced modeling using physically realistic assumptions generate more accurate and reliable results for interconnection forces. Navier-Stokes based solutions outperform traditional Reynolds equation approaches for thin films, including nonlinear time/frequency dependent characteristics.
