Liquid rocket shaking parameter acquisition and anti-shaking design method based on simulation data

The invention relates to a simulation data-based liquid rocket shaking parameter acquisition and anti-shaking design method, which comprises the following steps of: designing an anti-shaking plate, calculating an initial shaking parameter according to an initial ballistic parameter, and determining an anti-shaking design scheme meeting design requirements; shaking simulation: carrying out batch simulation calculation on shaking parameters, and arranging to form piece-by-piece data; shaking parameter processing: acquiring a curve according to simulation calculation, and performing data fitting in combination with the model to identify key parameters; establishing a database, and establishing a shake parameter database according to the acquired data; and the database is used, coefficients and information are extracted according to needs, and corresponding shake parameter data are found in the database and acquired. According to the simulation data-based liquid rocket shake parameter acquisition and anti-shake d
