ODS and Modal Analysis
Description
Learn how to use operating deflection shape (ODS), finite element and modal analysis to troubleshoot and solve complex structural and rotating equipment problems. The material covered in this course goes beyond the requirements for ODS and Modal analysis subjects included in Category III - IV guidelines established by ISO 18436-2, "Condition monitoring and diagnostics of machine - Requirements for training and certification of personnel - Part 2: Vibration condition monitoring and diagnostics".
- Understand the theoretical basis for Modal Testing and Analysis as well as Modal Prediction using Finite Element Analysis
- Understand excitation methods, include impact and shaker testing, coherence, transmissibility, transfer functions, mobility, compliance, and accelerance
- Choose the appropriate excitation and response measurement techniques for the application in question
- Understand the fundamentals of Modal Parameter Extraction to determine natural frequencies, shapes, and damping. This will include checks of the FRF data for validity, application of Mode Indicator Functions, as well as SDOF and MDOF curve fitting methods.
- Create a Finite Element Modal Prediction Model Using FEMAP and NEi Nastran
- Set up and operate the data acquisition hardware and software for ODS and Modal data collection
- Calculate the linear spectra, cross spectra, coherence and transfer functions using software
- Apply Modal and Finite Element Analysis to practical real-world resonance problems
Student Reviews
I found the content and delivery to be excellent. Chad is extremely knowledgeable and really drives home the essential learning. I LOVED the hands on learning portion of the training. It helped me tremendously and I will be applying what I have learned in the field. I liked the practical portion of the exam as thats where the rubber meets the road. You need this to apply it to the job. All of the theory in the world doesn't help when your standing at the machine trying to figure out how to collect the data necessary. I think about Mescope training class would be an excellent addition to your program. I enjoyed the training as well as the people associated with Redwolf Reliability. Thank You!
