Publication on free vibrations ignoring damping! Detailed explanation using formulas.
This technical document introduces eigenvalue analysis. Eigenvalue analysis of structural vibration problems refers to the analysis that calculates the frequencies and deformation modes when a structure undergoes free vibration. These frequencies are called natural frequencies, and when external loads with frequencies close to these natural frequencies are applied, resonance phenomena occur. In real phenomena, structures vibrate at their natural frequencies while being damped during free vibration, but here we will explain free vibration while ignoring damping. 【Contents】 ■ About Eigenvalue Analysis *For more details, please refer to the PDF document or feel free to contact us.*
