47 - Eigen modes in Dynamic Analysis
Lee, Jae Young
This screen demo introduces an educational function of VisualFEA, related to usage of eigenmode, in dynamic analysis. A generalized eigenproblem is established from the dynamic equilibrium equation. The vibration modes are obtained from this eigenproblem, and the dynamic behavior can be represented as a time dependent combination of vibration modes. This video shows demonstration of the educational function to study the concepts and procedures of dynamic analysis based on mode superposition.
