More than ever, the engineering of rotating equipment is under pressure to deliver better performance with reduced noise/vibration and increased durability.
This free 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 free seminar, both simulation and test methods will be presented in an interactive, side-by-side format.
