Mastering Test Fundamentals: A Seminar Series

Gain insights into the core concepts of rotating machinery and the foundational principles of durability and fatigue with ATA Engineering and Siemens

Join ATA Engineering and Siemens to explore the fundamentals of test including rotating machinery as well as durability and fatigue during an immersive two-day seminar series. These exclusive, in-person events are your gateway to an enriching experience, offering a platform to connect with likeminded professionals in the testing community.

You are invited to sign up for either one or both days of this free seminar series, covering a different topic each day. Our agenda is crafted to deliver valuable insights through theoretical presentations, captivating live demonstrations, and extensive networking opportunities. These events will answer questions like:

• What is rainflow/cycle counting and how is it used?
• How can field data be used to design a shaker test profile?
• What is fatigue damage? How can fatigue damage be measured and replicated in a test?
• What is an order? How does it get measured?
• What is torsional vibration? What type of problems does it cause and how can these problems be solved?
• How can viewing data in the angle domain, rather than time domain, provide insight into problems?
• What unique frequency signatures are generated by electric motors?
