Free-Free Modal Analysis

Modal analysis is called the mother of all dynamic analysis because modal analysis is a prerequisite before performing any dynamic analysis. The modal analysis captures the dynamic characteristics of the vibrating system like natural frequency and mode shapes. The natural frequency is the inherent frequency of the vibrating system at which the system tends to […]
