How to Apply API Standards to Turbomachinery Rotor Dynamics for Lateral Analysis

View Recording

Whether you’re creating a new design, changing an existing one (through retrofits, rerates, etc.) or even running root cause analyses, rotor dynamics is a topic that needs special attention in the world of turbomachinery. With assemblies sometimes including multiple shafts, gearboxes, couplings, and so on it becomes crucial to predict qualitatively and quantitatively the behaviors of rotor trains when in operation.

Even before working on our own software for rotor dynamics analysis SoftInWay, Inc. has been interested and able to help its clients with lateral and torsional analyses along with bearing simulation. Now that the AxSTREAM® platform can fully model them we are doubling down on the work in this area for all kinds of machines including stationary ones for power generation, systems in motion like turbopumps in rockets, or even vertical pumps.

In this webinar, we will discuss the specific application of API standards to lateral analyses in rotor dynamics for turbomachines. These standards are published as guidelines and classified by type of machine to help engineers determine which simulations to run, how to run them, what results to pay attention to and what are considered safe vs. unsafe working conditions for the rotor assembly. Understanding these recommendations is necessary as they can be the difference between reliable equipment and very costly and potentially fatal failures.

The scope includes:

• Basic introduction and definitions of rotor dynamics including failure examples
• Walkthrough of major API standards linked to lateral analysis of turbomachines
• Key differences between lateral and torsional analyses
• Objectives and procedure for rotor dynamics
• Approach to modeling rotor-bearing systems
• Presentation of main simulations and results in lateral analysis

Who should attend?

• Engineers working on turbomachinery design and analysis who may not be familiar with basic aspects and rules of rotor dynamics
• Engineers working in the rotor dynamics field interested in refreshing and/or updating their knowledge on these fundamental concepts
• Engineering managers interested in keeping up with top of the line software able to run rotor dynamics simulations
• Engineering students showing an interest in mechanical design of turbomachinery and wanting to learn more about rotor dynamics before entering the workforce with confidence
