The frequency response … WebOct 7, 2024 · In ElastoDyn, the damping ratio is specified separately for every mode rather than as a full mass or stiffness matrix scaling, so, there is no reason to use Rayleigh damping with a mass-proportional term. I’m not sure I understand your second question regarding different damping approaches.
WebThe damping factor is typically in the range 0.4–0.8 since smaller values give an excessive overshoot and a large number of oscillations before the system settles down. Larger values render the system sluggish since they increase the response time. WebIn the absence of a damping term, the ratio k/m would be the square of the circular frequency of a solution, so we will write k/m = n2 with n > 0, and call n the natural circular frequency of the system. Divide the equation through by m: x¨+(b/m)x˙ + n2x = 0. Critical damping occurs when the coefficient of x˙ is 2 n. The damping ratio α
