Lateral Rotor Dynamics Analysis
We perform lateral rotor dynamics analysis to evaluate shaft deflection, bending modes, lateral vibration, bearing response, and rotor stability in rotating machinery. Our analyses help predict vibration behavior, identify resonance risks, improve rotor-support system performance, and reduce vibration-related failures in turbines, compressors, pumps, motors, and other high-speed rotating equipment.
What We Evaluate
Our lateral rotor dynamics analyses evaluate how rotating shafts move in the radial direction under operating conditions, helping engineers understand vibration behavior, critical speeds, mode shapes, bearing loads, and support system effects.
