WebThe factor introduces damping forces caused by the absolute velocities of the model and so simulates the idea of the model moving through a viscous “ether” (a permeating, still fluid, so that any motion of any point in the model causes damping). This damping factor defines mass proportional damping, in the sense that it gives a damping contribution … WebThe critical damping coefficient is the solution to a second-order differential equation that is used to evaluate how quickly the system will return to its original (unperturbed) state. For a single degree of freedom system, this equation is expressed as: where: m is the mass of the system. c is the damping coefficient. mouse fitting
