WebThe bilinear damping model also departs at the 43rd population. Among the remaining trilinear and quadlinear damping models, the trilinear model has larger number of particles than the quadlinear model at convergence. Hence, based on the relative frequency of particles, the trilinear damping model is a better choice among the two surviving models. WebFriction damping occurs when the friction between the sliding parts slows down the movement between parts, viscous damping occurs with resistance to fluid or airflow.
