EXPERIMENTAL MODAL ANALYSIS - maintenance.org

Experimental modal analysis has grown steadily in popu-larity since the advent of the digital FFT spectrum analyzer in the early 1970’s. Today, impact testing (or bump testing) has become widespread as a fast and economical means of finding the modes of vibration of a machine or structure.

Tool Box Training - How to Torque Electrical Connections

electrical connections is contained in two elements: start with clean contact surfaces, and apply the correct force. 3. When it comes to electrical connections there are many. Some of which are; (a) solid connections (e.g., bus bars), (b) lug connections (e.g., switchgears), (c) molded terminal connection (e.g., breakers), (d) screw terminals
