Rotor Dynamics Simulators

Campbell Diagram Simulator for rotor critical speeds: visualize whirl modes, gyroscopic effects, and engine-order intersections in real-time analysis.

Centrifugal Governor Simulator compares how vibration or acoustic response and frequency behavior shifts as the main assumptions change.

Shaft Critical Speed Simulator: Find the "critical speed" of a rotating shaft carrying a disc. Adjust the shaft diameter, span, disc mass and operating speed…

Rotating Unbalance Vibration Simulator: Analyse the unbalance vibration of spring-supported rotating machinery such as motors, fans and pumps. Adjust the rot…

When a fan, an impeller or a grinding wheel vibrates, the cause is almost always mass unbalance.

Calculate rotor critical speed and unbalance response. Input mass, stiffness, eccentricity, and damping. Visualize the response curve and see animations.

Solve torsional eigenvalue problems for 2- to 4-disc shaft systems. Computes natural frequencies, mode shapes and Campbell diagrams to find critical speeds.
