System Dynamics
ME 352 - Dynamics of Physical Systems - a dynamic system is any system that changes with time. This could be a simple mechanical system such as the classical mass-spring-damper system, an electrical circuit, or even a supply chain. The study of system dynamics models these systems and predicts the states of the system (speeds, currents, quantity of goods) at any point in the future.
Below is an example of a simple mass-spring-damper system and the derivation of the system equations. The mass, m, is initially at rest and a force, F, is applied to the mass to excite the system. The ultimate goal of this derivation is to determine the velocity at which the system oscillates and the forces in the mass, spring and damper until the system comes to rest. MathCAD was used to solve this problem.
