Basics of Structural Vibration Testing and Analysis

Time and Frequency Analysis Structural vibration can be measured by using electronic sensors that convert vibration motion into electrical signals. By analyzing the electrical signals, the nature of the vibration can be understood. Signal analy­sis is generally divided into time and frequency domains; each domain provides a different view and insight into the nature of the vibration. Time domain analysis

Structural Vibration an overview ScienceDirect

When the structural vibration modes are uncoupled and the global damping is lower than 30%, equivalent linear analysis can be used for design. Alternatively, more refined types of analyses should be adopted, such as nonlinear time history or complex modal analysis. In the present case study, the use of linear equivalent analysis was allowed.

Improvement for design of beam structures in

Demand for large vibrating screen is huge in the mineral processing industry. As bending and random vibration are not considered in a traditional design method for beam structures of a large vibrating screen, fatigue damage occurs frequently to affect the screening performance. This work aims to conduct a systematic mechanics analysis of the beam structures and improve the design method. Total
