Description

Technical Field

[0001] The present application relates to the technical field of sway parameter calculation, and in particular to a sway parameter processing method, device, electronic device, and storage medium. Background Art

[0002] During transportation, liquid sloshing within the tank can affect transportation safety, necessitating calculation of the tank's sloshing parameters. For example, in a large liquid-propellant launch vehicle, the liquid propellant accounts for the majority of the rocket's mass. During flight, external excitations such as rocket body vibration, engine thrust variations, and attitude adjustments can cause the tank's liquid to slosh.

[0003] To accurately control the rocket's attitude during flight and avoid the frequency range of liquid sloshing during design, thus preventing flight accidents caused by liquid sloshing, it is necessary to calculate the sloshing parameters of the liquid within the tank. Currently, the commonly used method for calculating sloshing parameters is theoretical analysis, which is inefficient. Furthermore, the accuracy of the sloshing parameters determined by existing theoretical analysis methods is significantly reduced when anti-sloshing panels or special-shaped tanks are added.

[0004] Therefore, the existing processing method cannot be applied to the calculation of sloshing parameters of tanks with different structures, and has the problems of low calculation efficiency and low accuracy.
