As modern rotating machinery is pushed to operate at higher speeds, tighter clearances, and greater power densities than ever before, engineers need dynamic modelling tools that can keep up with the pace. In this fast-paced live webinar, SoftInWay’s turbomachinery experts will demonstrate how to condense a complex rotating machine into a simple, but accurate, rotor-bearing model, allowing for the identification of resonance and stability risks in a design before a single part is made.

Using AxSTREAM RotorDynamics and AxSTREAM Bearing, we’ll model and analyze a single-stage turbine’s rotor–bearing system, simulate its intrinsic dynamic behavior, and refine it to reduce instability.

Throughout this webinar, you’ll see how small adjustments to key design parameters such as bearing clearance, bearing span, and shaft diameter can transform an unstable or marginally stable system into a robust, practical solution. We will demonstrate how integrated rotor dynamics and bearing analysis tools reduce development time, minimize manual rework, and increase confidence in stability margins. You’ll also see how analysis results can be evaluated against common API rotor dynamic expectations and stability acceptance criteria, helping teams identify potential compliance risks early in the development cycle.

Join this session to learn how to:

• Break down a complex rotor into a simple, accurate, mass-elastic model in AxSTREAM RotorDynamics
• Model journal bearings and couple them directly with your rotor dynamic model
• Identify rotor dynamic risks before prototyping and physical testing, via critical speed and stability analyses
• Interpret analysis results and subtly redesign your system to significantly improve dynamic performance
• Evaluate results against API-style rotordynamic review expectations (e.g., critical speed separation and stability margin checks)

Who should attend:

• Turbomachinery, propulsion, aerospace, automotive and mechanical engineers working with or interested in high performance rotating machinery
• Design leads and project managers looking to accelerate their rotor dynamic analysis workflows
• Current or prospective AxSTREAM users seeking an example of a typical rotor dynamic workflow
• Students, researchers and educators in rotating machinery disciplines who want a practical, software-driven demonstration

Whether you’re designing propulsion engines, turbomachinery, generators, motors, gearboxes, or API-governed rotating equipment, this webinar will show how to rapidly evaluate rotor stability, reduce dynamic risk, and make confident design decisions, before committing to hardware or physical testing.
