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 more experienced users, this course explains how to interpret vibration test specifications and apply them to a vibration test system. Subjects covered are sinusoidal vibration, random vibration, and shock / bump testing together with a background to the equipment required for each type of test, methods of control and simple fixturing.
The course puts an emphasis on practical aspects of vibration testing culminating in the opportunity for every delegate to set up and run a complete vibration test on your system.
