We perform critical speed calculations for rotating machinery to ensure safe and reliable operation. We identify resonance risks, propose design optimizations, and recommend measures to enhance dynamic stability and reduce vibrations. Our services are tailored to your specific needs.

Critical Speed Calculations

We provide comprehensive critical speed calculations for rotating machinery, focused on identifying resonance risks, ensuring dynamic stability, and optimizing performance. Our services help prevent excessive vibrations, extend equipment lifespan, and enhance overall reliability.

Analysis and Identification:

• Evaluation of the dynamic characteristics of the rotating system, including stiffness, mass, and damping.
• Identification of natural frequencies and their relationship to operating speeds.
• Analysis of how operating conditions—such as load changes, speed variations, and temperature fluctuations—affect dynamic behavior.

Calculations and Simulations:

• Precise calculation of critical speeds using analytical methods or numerical simulations (e.g., FEM).
• Simulation of rotor dynamic behavior as it passes through critical speed ranges.
• Assessment of the impact of imbalance, eccentricity, and other operational factors on vibration levels.

Design Recommendations and Proposals:

• Proposals for measures to reduce resonance risks, such as modifying stiffness, damping, or mass distribution.
• Recommendations for optimizing rotor, bearing, or mounting design to enhance stability.
• Suggestions for operational limitations to ensure safe speeds outside critical ranges.

Supply and Support:

• Delivery of detailed technical reports featuring comprehensive calculations, simulations, and recommendations.
• Technical support for implementing the proposed measures and design modifications.
• Consultation on maintenance and regular diagnostics to monitor the dynamic behavior of rotating equipment.

Applications:

• Optimization of the operation of rotating machinery, such as turbines, pumps, fans, or machine tools.
• Ensuring safety and reliability when commissioning new equipment.
• Diagnosis and resolution of vibration-related issues in existing systems.

Our critical speed calculations help you achieve safe, reliable, and efficient operation of your rotating equipment, minimize the risk of failures, and reduce operational costs.
