Experimental Testing Methods and Theoretical Analysis of Simple Beam with Natural Frequency and Inherent Vibration

Simple beam which with the cross-section and continuous structure,is usually used as an analysis tool of the vibration phenomenon.Dynamic analysis of simple beam with the application of theoretical analysis and experimental testing methods,can get natural frequency,vibration amplitude and critical damping of the continuous structure.To analyze the natural frequency,vibration,amplitude and critical damping can avoid sympathetic vibration,which leads to the furthest damage to the framework.It can also reach the intention to avoid vibration.Start with the natural frequency and inherent vibration of the simple beam with cross-section,which offered a useful method to start our research of vibration of complicated framework.
