Method and device for determining rocket simulation model

The invention provides a rocket simulation model determination method and device, and relates to the field of vertical recovery rocket modeling simulation. The rocket simulation model determination method comprises the steps of obtaining at least one basic model library component in a preset language model library; constructing at least one special model library in the rocket simulation model according to the at least one basic model library component; constructing at least one subsystem model of the rocket simulation model according to the at least one special model library; and according to the preset language, performing simulation processing on the at least one subsystem model to obtain a target rocket simulation model. According to the scheme, all subsystem models of the rocket simulation model are constructed through the preset language, the simulation efficiency of the rocket simulation model and the reliability and accuracy of the simulation result are improved, and meanwhile the model construction co
