Modal Analysis with Correlation
This one-and-a-half-day modal training class is a great introduction to the principles of modal analysis, from basic definitions to more advanced applications. This course will put the emphasis on practical considerations and presented concept will be demonstrated with live measurements on test structures; putting emphasis on the importance of pretest for full setup optimization and data quality. Featured topics includes (but not limited to) single and multiple degree of freedom systems, excitation techniques like simple two channels impact excitations or multiple channels shakers burst-random excitation, FRF Acquisition, damping estimation, measurement validation and modal parameter estimation (curve fitting), ODS vs Modal results.
This course is aimed at anyone who is planning on making structural test or has been in the field for a while but would benefit form a refresher class to better use the modern tool for ODS, OMA and Experimental Modal analysis. Basic knowledge of FFT analysis is a great plus.
Objectives
• Teach introductory modal testing theory and instrumentation basics
• Introduction to a successful test set-up strategy
• Proper technique for mobility measurements
• Understand modal data and how to interpret results
• Understand the connection of test data to simulation data through modal correlation
Prerequisites – Fundamentals of Acoustics and Vibration, NVH Trouble Shooting (is a plus), some experience in sound and vibration is encouraged
Participants – Those looking for an update on techniques and measurement strategies, along with those new to modal analysis. This class will fit the test engineer and CAE simulation engineer.
LDS Introduction to Shaker Based Vibration Testing
This two day course provides a practical introduction to the subject of vibration testing. Designed around the needs of engineers new to the subject of vibration testing and yet offering a useful refresher course for the more experienced user. This course explains how to interpret vibration test specifications and apply them to a vibration test system. Subjects covered are sinusoidal vibration, random vibration, mixed-mode testing and shock/bump testing together with a background to the equipment required and methods of control. It explains how to evaluate a product and your fixture along with slip tables and Head expander requirements. The course emphasizes the practical aspects of vibration testing - the realities, the problems encountered and the common mistakes which can be made. This course removes the mystique of vibration testing and replaces it with facts and common sense. Each delegate will receive a full set of modules as future reference material as well as a USB stick with the presentations and other useful information. The aim is to provide confidence to the new user and verification to the more experienced engineer.
Objectives
• Basic principles of vibration testing using shakers
• Explore fixturing/head expanders and the role it plays in the testing strategy
• How to configure a shaker profile for successful testing
• Show the working principles of an electrodynamic shaker
• Basic maintenance and service of a shaker system
Prerequisites – Fundamentals of Acoustics and Vibration and/ or basic knowledge of physics or an engineering qualification. Experience with data acquisition and measurement techniques
Participants – Those interested in a vibration test strategy, those who recently acquired shakers or are purchasing a shaker. Those tasked to work with shakers on a regular basis.
