Sloshing analysis and mechanical modeling of liquid cargo during lifting

摘要

When the acceleration of the liquid-filled container undergoes a step change, liquid sloshing is prone to occur. A sloshing linear dynamic model is put forward to predict the position change of center of mass of sloshing liquid. This modeling process uses a liquid static model and adds a time variable. The numerical simulation example finally verifies the feasibility of the mathematical model and shows that linear dynamic model has the ability to predict the displacement of the center of mass.
