Webfrictional coefficients. The frictional coefficient is assumed to be a function of the static frictional coefficient µ s, the dynamic frictional coefficient µ d and the exponential damping coefficient c, expressed as µ= d + (s − d)e −cv. These three parameters µ s, d and c are identified by minimizing a target function f = (x* i − ∑ ... 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. WebThe viscous damping coefficient is the coefficient c in the formula. F = − c v. where F is the damping force and v is the velocity. c depends on what causes the damping. If it is a spring in air, then it is likely to be proportional both to the viscosity of the air and to the relevant area of the the spring leading to the damping. opting out of the union
