Time-domain analysis

Definition

Time-domain analysis is a method used to study how a system responds over time to external forces or inputs. This approach allows for the examination of dynamic behavior, capturing important information such as the magnitude and direction of forces acting on a system, particularly in relation to mechanical structures like tethers in airborne wind energy systems.
