Are you interested in best practices for predicting and optimizing rotating machinery dynamics?

rotating machinery

Siemens PLM cordially invites you for an informative and educational day covering the process and best practices for predicting and optimizing rotating machinery dynamics.

This seminar can help you answer questions like:

  • What is an order? How does it get measured?
  • What is torsional vibration? What type of problems does it cause and how can they be solved?
  • How can viewing data in the angle domain, rather than time domain, give me insight into problems?
  • What kinds of unique problems do gears and bearings have? How can they be analyzed and solved?
  • What unique frequency signatures are generated by electric motors?
  • What issues do hydraulic pumps show?

In this seminar, both simulation and test methods will be presented in an interactive, side-by-side format.
