Zusammenfassung: | The invention discloses a method for acquiring shaking parameters of a rocket propellant and a computer readable storage medium, and the method comprises the steps: carrying out simulation calculation of the liquid shaking of the propellant in a rocket storage tank, and obtaining the time domain data of the shaking force and the time domain data of the shaking moment; performing n-order Fourier transform on the shaking force time domain data to obtain n-order shaking frequency; and performing establishment of a corresponding shaking equation and curve fitting matching on the shaking force time domain data, the shaking torque time domain data and the n-order shaking frequency to obtain the mass center position of the n-order shaking mass of the propellant. By the adoption of the method, the technical problem that in the prior art, the precision control of a rocket is affected due to the fact that the obtaining precision of the shaking parameters is low can be effectively solved.
