Definition

A linear dynamic analysis technique for multi‑degree‑of‑freedom systems that computes the time‑domain response as a linear combination (sum) of the system’s vibration modes, using modal coordinates and modal orthogonality to decouple equations of motion when damping is proportional or can be represented in modal form.
