SDOF: Damped Free Vibration. Overdamped and critical damped systems.

In the previous video, we discussed how to model a free vibration system in Ansys; however, in this
video, we will delve deeper into free vibration but with damping.
Damping refers to the energy dissipation in a vibrating system that reduces the amplitude of its
oscillations over time. Thus, it is an essential characteristic of realistic mechanical systems, and
understanding its effects is crucial for designing and analyzing these systems.
To model a free vibration system with damping, we first need to define the necessary equations of
motion that describe the system's behavior. These equations will consider several factors, including the
damping coefficient, the system's mass, and the supporting structure's stiffness.
Moreover, we will also introduce the concept of damping ratio, which measures the level of damping
in the system. This value is crucial for determining the critical damping, the minimum damping required
to prevent the system from oscillating indefinitely.
By understanding and analyzing the behavior of a free vibration system with damping, we can gain
valuable insights into the response of mechanical systems to external forces. This knowledge is essential
for designing and optimizing structures and systems that withstand various loads and stresses.
