| Abstract: | The structure design for sloshing suppression in a liquid propellant tank results in the nonlinear characteristics of liquid sloshing damping. Based on the frequency response functions curve fit method, an approximate method for extraction of sloshing model parameters about the problem of nonlinear damping is derived. Applying this method to estimate the sloshing model parameters of liquid in the tank with baffle for sloshing suppression, the value of these parameters may have enough accuracy suitable for engineering application. |
